SEX IN INDIAN LANGUAGE SAYS "kam"
how do you define...????like two WAYS...?
 UNVERSAL meaning.....????
 WORLDY meaning.......???
The desire and the ACT to carry it out (the desire).
This in totality can be temed as Kam. But Kam or Sex are vulgar or bad. There are others terms which represent it, Vasna, which defies the social bonds even.
By the way, if I may add, WE, the humans are the only ones who Have sex for even PLEASURE as compared to our our colleagues of the animal kingdom. So the earler meaning of the term Kam could have represented the act of procreation or giving birth to a new being, but of late , and in Indian context very ancient, we have to our credit KamaSutra and Ajanta n Ellore and many miniature paintings. Why for that matter Raas Lilla is an expression of Love for the Divine (I Not being an evolved person, would take it as love for my beloved, which most of the Sufi Poetry also speaks about including Bahjans of Meera Bai etc).
Dharma is wat I take as MY PATH OF FOLLOWING. So what I take as a meaning of any word, without hiddering others is the best way to comprehend it.
