The Self is Existence, your consciousness without space. Soul Truth (atma-vidya) purifies the mind to realize your true Self. Abiding in higher Truth like a lion, spiritual living flows out as unconditional love, honesty and compassion in action. For the nature of the Self is complete opposite of the mind ego, as shared by the Buddha in - good and evil
Spiritual growth means our spirit grew to include and feel for others. You gain higher knowledge to realize the wisdom of letting go of all knowledge (concepts). The direct path: Empty mind of all concepts, and simply remain aware of all that remains. Relaxed, one remains in the natural state (awareness of awareness), all the good qualities naturally.
The Self is always still silent indivisible awareness, with no layers, levels, stages, dimensions, sounds, colors, degrees, contrasts or concepts. Profoundly simple, without dualities (advaita) yet with infinite imagination (dvaita). That which moves (or changes) is not real (a dream). That which never moves (or changes) is real (silent still awareness).
If the screen moved (or changed), you could not view a movie. Before, during and after a movie, the screen remains the same (silent, still). Dreams (movies) are the Self-experiencing of the Self within Itself. At night you dream with eyes closed (svapam). During day you dream with eyes open (jagrat). Both appear in the Self alone (turiya, the screen, awareness).
