If even for a single moment you are not doing anything and you simply are, that’s what meditation is

Existence is that which happens, that which goes on happening.
Existence means that which goes on happening eternally. So anything that happens is Existence. You and everyone are happenings. This eternal happening is Existence.
There is no creator and no creation. Your birth is a happening, and your death will be a happening. Your being here is a happening. Your not being here will be a happening.

Correct your mind, the rest of your life will fall into place

When you recognize that there is a voice in your head that pretends to be you and never stops speaking, you are awakening out of your unconscious identification with the stream of thinking. When you notice that voice, you realize that who you are is not the voice (the thinker) but the one who is aware of it. – Eckhart Tolle

The quality of being alive, that’s God

God is that which happens, not the creator, but that which goes on happening.
God means that which goes on happening eternally. So anything that happens is God. You and everyone are happenings. This eternal happening is God. There is no creator and no creation. Your birth is a happening, and your death will be a happening. Your being here is a happening. Your not being here will be a happening. – Osho
