There is, quite literally, nothing to understand.
When we're in our true being, the purpose of life is to feel that every moment is the purpose.
When you realize what you are now, the issue of death will solve itself.
The truth is that you already are what you are seeking.
As you rest into stillness more profoundly, awareness becomes free of the mind's compulsive control, contractions, and identifications. Awareness naturally returns to its non-state of absolute unmanifest potential, the silent abyss beyond all knowing.
Real meditation is not about mastering a technique; it's about letting go of control.
