Translation

BG 3.42: The senses are superior to the gross body, and superior to the senses is the mind. Beyond the mind is the intellect, and even beyond the intellect is the soul.

Commentary

An inferior entity can be controlled by its superior entity. Shree Krishna explains the gradation of superiority amongst the instruments God has provided to us. He describes that the body is made of gross matter; superior to it are the five knowledge-bearing senses (which grasp the perceptions of taste, touch, sight, smell, and sound); beyond the senses is the mind; superior to the mind is the intellect, with its ability to discriminate; but even beyond the intellect is the divine soul.

This knowledge of the sequence of superiority amongst the senses, mind, intellect, and soul, can now be used for rooting out lust, as explained in the final verse of this chapter.
