A small bird with a red bonnet on its head came and perched on a rock opposite us. It waved its tail, turned its head anxiously in all directions, then glanced directly at us and as it did so, it grew bold and began to whistle softly, tauntingly at first; but soon it threw back its head, swelled its throat, and gazing at the sky, the light, burst into song with abandon. Everything vanished; nothing remained in the world save this bird and God: God, and a beak that was singing.
Indivisible oneness is the creative energy that turns a seed into a maple tree, or a watermelon or a human being or anything else that's alive. It's invisible, omnipresent, and absolutely indivisible. We can't divide oneness. Meditation offers us the closest experience we can have of rejoining our Source and being in the oneness at the same time that we're embodied. This means we have to tame our ego.
