Jnanendriyas - senses of perception

Jnanendriyas are:

1. eyes: seeing; this is based on Thejas. Thejas is divine - use it properly - see what is good.

2. ears: Hearing comes from Sabdha. Hear only what is good

3. nose: Fragrance: good smell improves health; foul smell causes illness and distemper

4. mouth / tongue: rasa; taste

5. skin: touch or sparsa; avoid unnecessary contact to avoid contamination; there is a divine electric current in man - "chit-sakti" or energy of consciousness - that gets contaminated when in contact with another body. Good of yours can mix with bad of theirs. This is partly the reason why Sages and Saints of yore left for the forests.
