Ancient Philosophy
Thousands of years ago the ancient holy men of India contemplated the question of whether nature is ultimately unified. These men were devoted to silence and the inner life, but the rishis lived much further in the past- they were responsible for writing the most ancient texts of Veda, or revealed Truth, such as Rig Veda, which may predate the Egyptian pyramids by several thousand years.
It is interesting to learn that the depth of consciousness which was known to the rishis were also captivating to the young Lord Rama, who was supposedly a divine incarnation, He begs the sage Vasishtha for the instruction into the nature of these secrets.
The rishis were knowledgeable about the fundamental nature of reality. They were like us just as capable of dividing nature up into space, time, matter and energy, but they turned their backs on such an approach, which so dominated our way of seeing and thinking about the world.
