From ether, evolved from the tanmātra of sound, the next change occurs under the impulse of time: the subtle essence of touch appears; from it arise air (vāyu) and the tactile sense of the skin.
In the course of time, when the subtle forms are transformed into gross forms, they become the objects of touch. The objects of touch and the tactile sense also develop after this evolution in time. Sound is the first sense object to exhibit material existence, and from the perception of sound, touch perception evolves, and from touch perception, the perception of sight. That is the way of the gradual evolution of our perceptive objects.
This verse explains that when ether (ākāśa), whose subtle essence is sound, transforms under the influence of time, the quality of touch manifests; from that touch, air (vāyu) is produced.
Kapila teaches Devahuti Sāṅkhya—an analysis of matter and spirit—by explaining the step-by-step evolution of subtle qualities (tanmātras), gross elements, and sense organs, helping her detach from material identification and turn toward liberation.
Seeing the senses as instruments shaped by material nature helps cultivate detachment—use touch and other sensations consciously, avoid impulsive sense-gratification, and redirect attention toward bhakti and self-realization.
