It's Da Science

Eric suggests referring to Krishna Consciousness as "a spiritual path".

Obviously the situation and the audience influence the most appropriate thing to say and to what depth of explanation you need to go.

My personal observation, in some of the circles that I move in, is that Science is starting to defend its brand vigorously.

Thinking about it a bit more, between grinding out xml files, you could think of the phrase "Science of Self Realization" like "Rolls-Royce of X".

Read Science as "Shizzle", as in "Yo Dawg, it's the shizzle" - so "Yo Dawg, it's da science!"

So it would be like "The Shizzle of Self-Realization", as in "The Topmost/Best of Self-Realization".

And that's basically the intention, and reason Science strikes back to stop itself from being turned into a generic term, like Band Aid or Xerox.

"Spiritual" beats "Religion". "Metaphysical" is pretty left brain, as is "Science" (watch out - trademarked!). It depends on who you are talking to.

"Systematic, comprehensive, consistent, fully documented" is a tongue-twister, as Eric points out. You hold this in reserve and don't use it as the "catch phrase" - but if you understand these points and can illustrate and justify them, you'll be well placed to explain why "of Self Realization processes Krishna Consciousness is the Shizz".
