Adi Shankara,
The Crest Jewel of Wisdom — The Power of Mind-Images
(1946)
“ The treasure of the bliss of the Eternal is guarded by the terrible serpent of personality, very powerful, enveloping the Self, with three fierce heads--the three nature-powers; cutting off these three heads with the great sword of discernment, guided by the divine teachings, and destroying the serpent, the wise man may enter into that joy-bringing treasure.So long as there is even a trace of the taint of poison in the body, how can there be freedom from sickness? In just the same way, there is no freedom for him who seeks union, while selfishness endures. ”
