Jesus covenant with his disciples was not kundalini related, it integrity related;
"However, YOU are the ones that have stuck with me in my trials;  and I make a covenant with YOU, just as my Father has made a covenant with me, for a kingdom,  that YOU may eat and drink at my table in my kingdom, and sit on thrones to judge the twelve tribes of Israel." Lk22:28

Jesus gave a biology lesson? Wasn't he more inclined to spiritual instruction;
"“On this account I say to YOU: Stop being anxious about YOUR souls as to what YOU will eat or what YOU will drink, or about YOUR bodies as to what YOU will wear. Does not the soul mean more than food and the body than clothing? 26 Observe intently the birds of heaven, because they do not sow seed or reap or gather into storehouses; still YOUR heavenly Father feeds them. Are YOU not worth more than they are? 27 Who of YOU by being anxious can add one cubit to his life span? 28 Also, on the matter of clothing, why are YOU anxious? Take a lesson from the lilies of the field, how they are growing; they do not toil, nor do they spin; 29 but I say to YOU that not even Sol′o·mon in all his glory was arrayed as one of these. 30 If, now, God thus clothes the vegetation of the field, which is here today and tomorrow is thrown into the oven, will he not much rather clothe YOU, YOU with little faith? 31 So never be anxious and say, ‘What are we to eat?’ or, ‘What are we to drink?’ or, ‘What are we to put on?’ 32 For all these are the things the nations are eagerly pursuing. For YOUR heavenly Father knows YOU need all these things.
33 “Keep on, then, seeking first the kingdom and his righteousness, and all these [other] things will be added to YOU. 34 So, never be anxious about the next day, for the next day will have its own anxieties. Sufficient for each day is its own badness." Mt6:25

Very Important Parable for our time................We have been Warned to stay Awake!.........................

Jehovah's kingdom to come and the 1,000 year reign of Christ is the greatest invitation ever offered to mankind. Politics and religion divide the world ultimately leading to our own self inflicted destruction;
"Also, there will be signs in sun and moon and stars, and on the earth anguish of nations, not knowing the way out because of the roaring of the sea and [its] agitation, 26 while men become faint out of fear and expectation of the things coming upon the inhabited earth; for the powers of the heavens will be shaken. 27 And then they will see the Son of man coming in a cloud with power and great glory. 28 But as these things start to occur, raise yourselves erect and lift YOUR heads up, because YOUR deliverance is getting near.” Lk21:25

Actually it was about Prepping for the End Times.
It has both a Physical and a Spiritual meaning!
The foolish are never prepared when something unexpected happens. The Wise Always Are.

The context is the Last days and the return of Christ.
So what else did he say about this?

Mat 24:3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?

Mat 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
Mat 24:16 Then let them which be in Judaea flee into the mountains:
Mat 24:17 Let him which is on the housetop not come down to take any thing out of his house:
Mat 24:18 Neither let him which is in the field return back to take his clothes.
Mat 24:19 And woe unto them that are with child, and to them that give suck in those days!
Mat 24:20 But pray ye that your flight be not in the winter, neither on the sabbath day:
Mat 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
Mat 24:22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.

If you flee with nothing you will suffer and Die.
So if you see the time approaching, and are wise, you would be ready to flee. you would not need to return to your home to pack things, to flee with.
Spiritually, you would be ready to "meet your Maker", being prepared for the life after Death.

exactly,be prepared,............................

Two men are sleeping in a bed, The Flesh is left The Spirit goes to be with Jesus.

Two women are grinding wheat, The Flesh is left, The Spirit goes to be with Jesus.

FLESH AND BLOOD CANNOT ENTER HEAVEN

That's quite an expression, but most who will be granted deliverance thru Armageddon will make it alive.
Here's another description of preparedness.... spiritually;

"And I saw three unclean inspired expressions [that looked] like frogs come out of the mouth of the dragon and out of the mouth of the wild beast and out of the mouth of the false prophet.  They are, in fact, expressions inspired by demons and perform signs, and they go forth to the kings of the entire inhabited earth, to gather them together to the war of the great day of God the Almighty.
  “Look! I am coming as a thief. Happy is the one that stays awake and keeps his outer garments, that he may not walk naked and people look upon his shamefulness.”
 And they gathered them together to the place that is called in Hebrew HarMagedon." Rv16:13

In short...both.

Yes that's probably the best answer because it is a warning to the 'believers' that they worship in vain their own way, and it encourages Jesus' real disciples to continue Serving him in the kingdom preaching work. The 'oil' of enlightenment means both accurate knowledge of trith, and sharing it freely;
"I solemnly charge you before God and Christ Jesus, who is destined to judge the living and the dead, and by his manifestation and his kingdom, 2 preach the word, be at it urgently in favorable season, in troublesome season, reprove, reprimand, exhort, with all long-suffering and [art of] teaching. 3 For there will be a period of time when they will not put up with the healthful teaching, but, in accord with their own desires, they will accumulate teachers for themselves to have their ears tickled; 4 and they will turn their ears away from the truth, whereas they will be turned aside to false stories. 5 You, though, keep your senses in all things, suffer evil, do [the] work of an evangelizer, fully accomplish your ministry.

Only a very small remnant of those invited to heaven to serve as assistant kings to Jesus remain on earth. The illustration mainly applies to his his disciples approved to inherit the earth;
"After these things I saw, and, look! a great crowd, which no man was able to number, out of all nations and tribes and peoples and tongues, standing before the throne and before the Lamb, dressed in white robes; and there were palm branches in their hands. 10 And they keep on crying with a loud voice, saying: “Salvation [we owe] to our God, who is seated on the throne, and to the Lamb.”
.... “These are the ones that come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb. 15 That is why they are before the throne of God; and they are rendering him sacred service day and night in his temple; and the One seated on the throne will spread his tent over them. 16 They will hunger no more nor thirst anymore, neither will the sun beat down upon them nor any scorching heat, 17 because the Lamb, who is in the midst of the throne, will shepherd them, and will guide them to fountains of waters of life. And God will wipe out every tear from their eyes.” Rv7:9

At that point the decision of who was accepted will already have been made so don't anyone be thinking that will be the time to respond;
"When the Son of man arrives in his glory, and all the angels with him, then he will sit down on his glorious throne. 32 And all the nations will be gathered before him, and he will separate people one from another, just as a shepherd separates the sheep from the goats. 33 And he will put the sheep on his right hand, but the goats on his left.
34 “Then the king will say to those on his right, ‘Come, YOU who have been blessed by my Father, inherit the kingdom prepared for YOU from the founding of the world.

..... “Then he will say, in turn, to those on his left, ‘Be on YOUR way from me, YOU who have been cursed, into the everlasting fire prepared for the Devil and his angels. ... And these will depart into everlasting cutting-off, but the righteous ones into everlasting life.”
When the Son of man arrives in his glory, and all the angels with him, then he will sit down on his glorious throne. 32 And all the nations will be gathered before him, and he will separate people one from another, just as a shepherd separates the sheep from the goats. 33 And he will put the sheep on his right hand, but the goats on his left.
34 “Then the king will say to those on his right, ‘Come, YOU who have been blessed by my Father, inherit the kingdom prepared for YOU from the founding of the world. 35 For I became hungry and YOU gave me something to eat; I got thirsty and YOU gave me something to drink. I was a stranger and YOU received me hospitably; 36 naked, and YOU clothed me. I fell sick and YOU looked after me. I was in prison and YOU came to me.’ 37 Then the righteous ones will answer him with the words, ‘Lord, when did we see you hungry and feed you, or thirsty, and give you something to drink? 38 When did we see you a stranger and receive you hospitably, or naked, and clothe you? 39 When did we see you sick or in prison and go to you?’ 40 And in reply the king will say to them, ‘Truly I say to YOU, To the extent that YOU did it to one of the least of these my brothers, YOU did it to me.’
41 “Then he will say, in turn, to those on his left, ‘Be on YOUR way from me, YOU who have been cursed, into the everlasting fire prepared for the Devil and his angels. 42 For I became hungry, but YOU gave me nothing to eat, and I got thirsty, but YOU gave me nothing to drink. 43 I was a stranger, but YOU did not receive me hospitably; naked, but YOU did not clothe me; sick and in prison, but YOU did not look after me.’ 44 Then they also will answer with the words, ‘Lord, when did we see you hungry or thirsty or a stranger or naked or sick or in prison and did not minister to you?’ 45 Then he will answer them with the words, ‘Truly I say to YOU, To the extent that YOU did not do it to one of these least ones, YOU did not do it to me.’ 46 And these will depart into everlasting cutting-off, but the righteous ones into everlasting life.” Mt25:31
