It can't possibly mean anything, because it isn't possible. I say this as someone who has been very much "into" this stuff for decades, I have studied scores of religions, practices and philosophies, and have become somewhat good at some of these things. The more I learn, the more I realise that "lack of desire" is just as extreme (and misguided) as the western-style obsession with desire.

My conclusion is this: desire is the fundamental force driving all of life. It's foolish to fight it. Embrace it. But only after you've realised that you are NOT it.
