Often we hear, "Is there a right time to die?" Of course there is: when one has been invited back home. When the Universal is waiting. The Light will invite you. The Doorway will open. You will know this with either your senses or your intuition or both. You will look outward ata the world and experience a sense of peace that only the opened Doorway and the Light can provide.
Meditation is basically the practice of quieting the mind on deeper and deeper levels until we reach the underlying, subtle consciousness that is the root of all things. But a quiet mind does not mean the absence of thoughts. It means a mind that does not interfere with or distort the natural flow of sensations, feelings, perceptions, images, and thoughts through the open field of our consciousness. A quiet mind is a clear space, a mirror for the entire experience of inner and outer life.
