Every living entity is sanātana; the Personality of Godhead, He is also sanātana; and the system, or the modus operandi which we execute, is that to achieve that final goal how we can again unite together, both sanātanas—the jīva and the Supreme Personality of Godhead. This unification does not mean that we become amalgamated, homogeneous. No. This unity means that in the conditioned state of our existence, or in our material life, we do not agree to the proposal of the Supreme Personality of Godhead. The Supreme Personality of Godhead says, Kṛṣṇa,
- sarva-dharmān parityajya
- mām ekaṁ śaraṇaṁ vraja
- ahaṁ tvāṁ sarva-pāpebhyo
- mokṣayiṣyāmi mā śucaḥ
- (BG 18.66)
But so long we do not agree to this proposal—the open offer by the Supreme Personality of Godhead—that is our material existence. Material existence and spiritual existence does not mean that in our material existence we have got two hands and in our spiritual existence we shall have four hands, or something different. It is not like that. Spiritual existence means to agree with the offer or proposal by the Supreme Godhead. This is unity, unity of agreement. Not that we become one. One in agreement.
In the second chapter of Bhagavad-gītā you will find that the Supreme Personality of Godhead, Kṛṣṇa, says to Arjuna, "My dear Arjuna, you, Me, all these kings and the soldiers who are now assembled here, it is not that they were not existing in the past, neither it is that they will cease to exist in the future." That means Kṛṣṇa, Arjuna and the other living entities, all of us, nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13), we are all individuals. Kṛṣṇa is individual, you are individual, I am individual—everyone individual.
And we have got individual independence also. Pūrṇasya pūrṇam ādāya (Īśo Invocation). Kṛṣṇa is so perfect that whatever He creates, that is also perfect. So if we are supposed to be created by God, or Kṛṣṇa, then perfectly we have got all the qualities of Kṛṣṇa—but in minute quantity. That is the difference. We have got all the qualities. You can study Kṛṣṇa simply by studying your qualities. Whatever quality you have got, Kṛṣṇa has got also the same quality. The difference is that you have got them in minute quantities, and Kṛṣṇa has got them in full quantities. That is the difference.
Therefore unity, or to become one with Kṛṣṇa, means that we agree to His proposals. It is very simple to understand. Just like in the family: the head of the family, and there are many members, sons and daughters or servants, wife, children, so many. If all the family members agree to the proposal of the prime person, the family life is very peaceful. Similarly God is the center, Kṛṣṇa is the center. Ahaṁ sarvasya prabhavaḥ (BG 10.8): from Him everything is coming, everything is emanating.
The Vedānta-sūtra also says, janmādy asya yataḥ (SB 1.1.1). That is parabrahman, Absolute Truth. The same example: just like in a family, the father is the chief man, and from him every children is coming out. Similarly in the creation, either material or spiritual, Kṛṣṇa is the center, sarva-kāraṇa-kāraṇam (Bs. 5.1), and the world should be one family, and Kṛṣṇa the head. That is the ideal. That is ideal communism or socialism.
