The state of Yoga is part of another dimension where what we normally identify with as being “me” or “I” is actually just waves.. This reality is not theoretical it is experiential. As we sense this we may cling to those fleeting identities all the harder. It takes long practice, faith/trust, courage and detachment to see ‘what happens when we let go?’
“When the water of a lake is unruffled, the reflection of the moon on its surface is very clear. Similarly, when the lake of consciousness is serene, consciousness disseminates itself. This is known as a glimpse, or a reflection, of the soul.
The seer, being constant and unchangeable, can perceive the fluctuations as well as the serenity of his consciousness. If consciousness itself were self-luminous, it too could be the knower and the knowable. As it has not the power to be both, a wise yogi disciplines it, so that he may be alive to the light of the soul.
It is said in the Bhagavad Gita (II.69)‘One who is self-controlled is awake when it appears night to all other beings, and what appears to him as night keeps others awake’. A yogic sadhaka thus realizes that when consciousness is active, the seer is asleep and when the seer is awake, it is night to the consciousness.
Similarly, in the Hatha Yoga Pradipika, the word ha is used to signify the seer as the ‘sun’, which never fades; while tha represents consciousness as the ‘moon’, which eternally waxes and wanes.” Excerpt From
