You cannot split the Earth by drawing boundaries on it.
 - Tukaram

1. We live on a planet that supports life and look for other planets that support life, anywhere in reachable space, in imaginable terms. We try to imagine another Earth and another mirror of life. For, supporting our life, the Earth becomes the very foundation of our awareness, the source of our being.

2. Our knowledge of ourselves cannot surpass our knowledge of the Earth, of which we are a mere detail. Richly detailed by life, the Earth may be conceived as an evolving art form and this, I suppose, is Tukaram's perception. However interconnected above or beyond the Earth, all the forms of life that spring from the Earth share it as their origin and their heritage.
