The day will come when you'll see the realities of the spiritual world with the same clarity, as you see the realities of the physical plane

"It is not enough for an initiatic teaching to inform you of the existence of the different subtle bodies you have beyond your physical body. It must give you criteria for discerning the quality of your states of consciousness and their corresponding thoughts and emotions. And it must also give you methods to develop your spiritual organs, which will enable you to cross the region of illusory perceptions and reach the regions of soul and spirit with assurance.
After much work and many exercises, the day will come when you will see the realities of the psychic and spiritual world with the same clarity, accuracy and precision as you see the realities of the physical plane. And that is when you will contemplate true life; you will see all things as a whole, and when you have to explain or describe them you will present the exact truth."
