There is no need to ascend or ascend anything to know truth. It is within everyone and all that has to be done is to let go of concepts that block the truth. It is the holding to ideas that keeps one blind to truth. That is why meditation is so valuable. It forces one to self inquire which leads to a natural self cleansing process. All must dissolve before truth can be re-known. It takes the clouds (concepts) and moves them or dissolves them away so that the sun (truth) can shine like it always has. Truth is always here. It has never left you. You have just forgotten it by your clinging to ideas. It is your ideas that keep you from it. Meditation is the way out. It allows space around thoughts so the light can penetrate and dissolve them.
