Shri Krishna listed the qualifications of a seeker in the prior shloka, and asserted that one who takes his refuge will attain his abode. He now provides the location, the address of that abode. He says that there is no sun, no moon, no fire, in other words, no source of light in his abode. Initially we would feel a little frightened if we take the literal meaning of this shloka. Even cavemen were able to access some light source in the form of the sun, the moon, or fire from a wooden torch. Why would anyone want to go to such a place?
 
The sun, the moon and fire have symbolic interpretations which are extremely relevant here. The sun is the presiding deity of our intellect, the moon of our mind and emotions, and fire of our physiological functions. The one who has sought refuge in Ishvara automatically gives up affinity to his body, mind, intellect, ego (which resides in the intellect) and physiological functions. If this affinity, the root of all our sorrow, is given up, such a person will never again get caught in the wheel of birth of death, in the cycle of samsaara. This is liberation.
 
So then, this is the abode of Ishvara, of self realization, of liberation. Having reached there, the liberated person does not come back to the state of ignorance. He never gets deluded again. He never identifies or develops affinity with body, mind, intellect and the world. The duality, the pairs of opposites, the dvandva that was mentioned before, is nothing but the world. For such a person, neither joy nor sorrow, neither pain nor pleasure, neither friend nor enemy, nothing can destabilize him. This is liberation.

Arjuna understood that the source of nature’s power was none other than Ishvara. He saw Ishvara in all the primal forces of nature and listed their presiding deities: Vayu, the lord of wind who sustains all living beings. Yama, the lord of death who ensures justice for everyone. Agni, the lord of fire who provides energy to all beings. Varuna, the lord of life-giving water. Shashaanka, the moon, who nourishes all plants and herbs.
 
How could Ishvara manifest as all these deities? Because Ishvara functions as Prajaapati, also known as Lord Brahmaa, creator of the universe who brought all the deities into existence. Vedic texts refer to Brahmaa as Hiranyagarbha, the golden womb that brought forth the universe. But Ishvara existed even before Brahmaa was created, he is the Prapitaamaha, the great-grandfather, the original person.
 
When we are humbled, when we come in the presence of someone who is infinitely more capable than we are, we could have one of two reactions. If we have no respect for that person, we could harbour feelings of resentment and anger. But in this case, Arjuna was humbled by Ishvara for whom he had the utmost reverence. Knowing that the source of the universe was on his side, all he could do was repeatedly prostrate and offer his salutations. Knowing that it was Ishvara who was doing his work all along, Arjuna’s completely surrendered his pride.
