Indriyani mano buddhir asyadhisthanam ucyate
etair vimohayaty esa jnanam avrtya dehinam
(Text 40, Ch 3, Karma Yoga)
Meaning: The senses, the mind and the intelligence are the sitting places of this lust. Through them lust covers the real knowledge of the living entity and bewilders him.
*** Mind is the center of all the activities of the senses, and thus when we hear about sense objects the mind generally becomes a reservoir of all ideas of sense gratification; and as a result, the mind and the senses become the repositories of lust. Next, the intelligence department becomes the capital of such lustful propensities. Intelligence is the immediate next-door neighbor of the spirit soul. Lusty intelligence influences the spirit soul to acquire the false ego and identify itself with matter, and thus with the mind and senses. The spirit soul becomes addicted to enjoying the material senses and mistakes this as true happiness.
