Panchadashi 2.11

Tongue, hands, legs, anus and genitals, these organs fulfill those actions. It is due to those actions that these organs are asserted. Face, hands, legs, anus and genitals are the containers in which these five organs of action reside.

Panchadashi 2.10

Speech, grasping, movement, excretion and union, these five activities of man are well known. Agriculture, trade and service and other activities are incorporated in these five categories.

Panchadashi 2.8, 2.9

When the ears are closed, breath sounds as well as sounds of the stomach digesting food can be heard. When we drink water or eat, we can feel the touch of those materials inside our body. When we belch, the taste and smell of what is inside is senses. In this manner, senses can imbibe what is inside our bodies as well.

Panchadashi 2.6, 2.7

Hearing, skin, eyes, tongue and nose, all these five senses reside in ear and other holes. They imbibe sound and other qualities. Since these senses (since they are made of non-grossified elements) they are so subtle that they are invisible. They can only be inferred from their effects.

These senses usually are externally oriented and run after external objects.

Panchadashi 2.3-2.5

In space, the notion of echo is called sound. Space only has one quality.

Wind has a sound like "bee see", and has the quality of touch without any temperature - 2 qualities.

Fire has a sound like "bhugu bhugu", the qualities of warm touch and the form of the red colour - 3 qualities.

Water has a sound like "bula bula", the qualities of cold touch, white colour and sweet taste - 4 qualities.

Earth has a sound like "kada kada", the qualities of rough touch, blue and other colours, it is sweet, sour etc. to taste - 5 qualities. 

Panchadashi 2.2

Sound, touch, form, taste and smell, these are the qualities of space and the other elements. In space and others, there are one, two, three, four and five qualities respectively.

Panchadashi 2.1

That non-dual reality which has been explained in the shruti is known only by the discrimination of the five elements. All five elements are being discriminated now.

"Sadeva .." with this shruti, prior to the creation of the world, we get the information of the non-dual brahman which is the cause of the world, since it is not the object of mind or speech, no one can gain direct knowledge of that brahman.

That is why, since the five element are its effect of it, we can only know brahman by discriminating the five elements. With that alone, these five elements are now being discriminated, with a view to realize that brahman.
