Some [the unadulterated brahmacaris] sacrifice the hearing process and the senses in the fire of mental control, and others [the regulated householders] sacrifice the objects of the senses in the fire of the senses.
Others, who are interested in achieving self-realization through control of the mind and senses, offer the functions of all the senses, and of the life breath, as oblations into the fire of the controlled mind. (Bhagavad Gita 4:24-27; emphasis added[i])
No hands, no feet on earth but yours. Yours are the eyes through which he looks compassion on this world. Yours are the feet with which he walks about doing good. Yours are the hands, with which he blesses all the world.
A faculty and its object are like the primordial couple. The relationship of the eye to what is seen is the relationship of Shiva to his shakti. The ear and music, the eye and art, the tongue and flavour, all senses and their sensations are a participation in the eternal embrace.[ii]
I was reflecting upon how arduous a life this is…I said to myself, “Lord, give me some means by which I may put up with this life.” He replied, “Think, daughter, of how after it is finished you will not be able to serve me in ways you can now. Eat for Me and sleep for Me, and let everything you do be for Me, as though you no longer lived but I; for this is what St. Paul was speaking of.”[iii] (1 Cor. 10:31)
