I’ll answer this.
It’s not about having no desires. It’s about not holding deep attachments to the outcome of those desires. Let them flow, gently. Sometimes you will achieve the object of your desire, sometimes you won’t. Regardless of whether you achieve them or not, the state will change. Living lightly within that inevitability makes life easy.
It isn’t actually the desire that causes the suffering. It’s the attachment one must avoid. If you open yourself to the possibility that what you desire might actually manifest in a way that’s different (but no less wonderful), you leave the door open to much more than you ever desired.
Oddly enough, I knew all this stuff intuitively (but not at all consciously) when I was young. It took losing pretty much everything to understand. I’m still struggling to get back to the state of grace I lived most of my life in. It’s been a lot harder for me to achieve that state in a conscious, intentional way than it ever was to just live it. Knowledge, it turns out, can’t hold a candle to intuition when it comes to finding peace and balance in life.
