It can happen with a roseflower, it can happen with a rock, it can happen with the trees, it can happen with anything. Once you know the situation in which it happens, it can happen anywhere. If you know that you are not, and with a deep love your consciousness has moved to the other - to the trees, to the sky, to the stars, to anyone; when your total consciousness is addressed to the other it leaves you, it moves away from you - in that absence of the self is the blessing.
