Death may call any moment. Every moment, everyone is nearing death.
Swami cannot give peace of mind; you must work for it yourselves. First, stop the questioning and ask, 'who am I?'. This is my body, my mind, my intelligence. But who is this 'My'? Who is it that claims the ownership of that which is declared to be 'mine'? 'My' indicates ownership. That 'My' is the life. As long as the life is in the body, there is this connection between the 'my' and the intellect - 'my' body, 'my' house, 'my' land. But the moment you remove the life from the body, there is no 'my' or sense of possession. Life is God.
Every moment is the right moment.
On previous occasions when God incarnated on earth, the bliss of recognizing Him in the incarnation was vouchsafed only after the physical embodiment had left the world, in spite of plenty of evidences of His Grace. But, ponder a moment on this Sathya Sai Manifestation; in this age of rampant materialism, aggressive disbelief and irreverence, what is it that brings to It the adoration ofs from all over the world? You will be convinced that the basic reason for this is the fact that this is the Supra-worldly Divinity in Human Form.
