Introduction
Kṛṣṇa again and again talks about the true nature of the Self. He tells Arjuna that the soul is free from all entanglements. It is eternal and transcendental. Kṛṣṇa says that though the soul has come into contact with the material body, it still is free.
Kṛṣṇa says that just as the sun illuminates our whole world, one Supreme Self— Paramātma, that is one kṣetrajña, illuminates all beings in the Universe, whether they are animate or inanimate. He says everything has the same consciousness.
Kṛṣṇa gives more and more examples. The sun sheds light on the surrounding planets. The darkness on the planets is removed by the sun's light. In the same way, the Supreme Self, kṣetrajña, lights up all beings in the Universe. The ultimate consciousness lights up the entire Universe. All beings of the Universe have this consciousness.
