Here's my personal interpretation of Hindi deity Shiva, based on a little bit of personal experience.

While living in my Japan, my Indophile friends told me about Shiva having saved a village by drinking a sea of poison (to me this represents imbibing alcohol).

It's also well known that Shiva loves smoking ganja.

For these obvious, and other, more subtle, reasons, Shiva strikes me as a god of intoxication and communion through inebriation.

In this sense, to get high is to commune with Shiva. Of course, it's just one interpretation of many, so...

Here's a song of mine made in reverence of this concept.

OM NAMA SHIVAI ~BOM!
