Self-awareness is the foundation of spiritual development and awakening.
Self-awareness is neither difficult nor complicated.
The challenge is to remember to be aware of Ourselves (true Self, Atman) and of ourselves (egoic self and its content).
To remain as much as possible in self-awareness and deepen into it, is required constant vigilance and great interest, at least greater than to identify with mind and sense objects and experience pleasure. Because without identification pleasure isn't possible. Without identification there is only pleasant and unpleasant experiences.
So like all things in life we have to choose what is more important for us, what we really want in life: identification and pleasure or self-awareness and fulfillment, peace, and bliss?
