Listen closely to the wisdom of the senses and the subtle workings of the mind. The ear exists for hearing, receiving the sounds of the world; the skin is for touch, perceiving sensations. The eye is given for seeing, and the mind, ever active, forms doubts and questions. Even what is seen above, below, or in the water by the soles of the feet—all these perceptions arise through the senses and their contact with the world. It is necessary for men to thoroughly understand these senses, for in their understanding lies the key to deeper knowledge. A wise man, armed with this understanding, perceives the coming and going of all beings, seeing the cycles of existence with clarity. Yet, know that understanding can be destroyed by the qualities, and likewise, understanding can diminish the senses themselves. All that exists—whether moving or unmoving—is pervaded by That, the underlying reality. The eye is called so because it enables sight; the ear, because it enables hearing. Through the skin, touch is perceived, and the intellect, ever agile, transforms in an instant. From the foundation of intellect arise the five distinct objects of sense, each with its own nature. The intellect abides within the person and operates in three modes. It does not, at any time, become entangled in pleasure or pain. This intellect, shaped by the modes, does not transcend these three states. When the intellect moves beyond them, it still functions among the modes within the mind, always activating the senses. Whatever modes exist in this world, all are encompassed within these three. The wise must master all the senses, for the threefold perception of the universe is seen in all beings. Contact with happiness arises from the quality of sattva; contact with pain springs from the quality of rajas. Whatever brings delight to you, whether in body or mind, and whatever brings pain and displeasure, and whatever is joined with delusion, indistinct and troubled—all these have their roots in the qualities. Exultation, joy, bliss, happiness, tranquility of mind—these states; as well as discontent, distress, sorrow, greed, and forbearance; disrespect, delusion, heedlessness, sleep, and drowsiness—these many faults arise, all rooted in desires and doubts. The distinction between sattva and the knower of the field, though both subtle, is likened to a mosquito and a fig: always joined together, yet by their nature, separate. The qualities do not know the self, but the self knows all the qualities. The senses act for the sake of illumination, together with pure intellect. Sattva produces the qualities, while the knower of the field observes them. Neither sattva nor the knower of the field has any true support; they exist in their own way. When one restrains their rays with the mind in the right way, the sage, ever delighting in the self and having abandoned natural action, becomes free—just as a bird living in water is not wetted by the water. So too, a person should dwell in their own nature, with their own understanding. By the method of contemplation, one constantly produces the qualities; yet when they are destroyed, they do not return, and true cessation is not found. Thus, some conclude this is cessation, while others think otherwise.
