Yoga Sutras of Patanjali translated by Yogi Kalinath - Chapter 4, Verse 28
Pada 4, Sutra 28
Haanam esaam kleshavad uktam
The cessation of these subconscious impressions is achieved as described for the causes of afflictions.
Involution is the key to spiritual unfoldment. While evolution is the key to expression and adaptation in the embodied state in the physical universe, involution is the withdrawing of consciousness into the subtle realm peeling away the layers to the kernel of the Self. What creates disturbance or the afflictions of the mind are our identification with the fluctuations and movements of the mind solidified into an illusory identity called the ego.
Equanimity is real wealth and the Key to the Kingdom of Heaven Within.
