Two basic principles or deep laws that govern the Universe,
1. First is Rita - Regularity or order or law.
The Universe displays discipline.
Without it no scientific or moral discovery would be possible &
Human 'experience' would have no meaning, as there would be no learning.
2. The Second is Yajna - Sacrifice.
The Universe runs on renunciation.
The most significant human Action is sacrifice of personal gain for
something higher or holier.
If, Rita, regularity is the moral law governing the universal existence,
then Yajna, renunciation is the human response to live in accordance with the law.
We can use things,
but to be in harmony with the underlying laws of Life,
We should never feel that they are really ours.
Everything belongs to the Existence.
