In plain words: The mind does not shine with its own light. It is something that is seen. Only the Purusha, the true Self, gives light and awareness to the mind and everything else.
Tremendous power is manifested everywhere in nature, but it is not self-luminous, not essentially intelligent. The Purusha alone is self-luminous, and gives its light to everything. It is the power of the Purusha that is percolating through all matter and force.
Namaste.
A calm guide to life, the mind and the old teachings.
