The aim of life is tattva-jijñāsā. That Sanātana Gosvāmī did when he approached Śrī Caitanya Mahāprabhu. He inquired from Him, ke āmi kene āmāya jāre tāpa-traya: "My dear Lord, kindly let me know who am I and why I am put into the threefold miserable condition of life." Then one can say, "You are minister. You know what you are." Then he says, "No, actually I do not know what I am." Grāmya-vyavahāre paṇḍita tāi satya māni: "Some neighborhood men, they call me I am very big man, I am very learned man, and when I study myself," āpanāra hitāhita kichui nā jāni, "I do not know what I am, wherefrom I have come, where I have to go after leaving this body, why I am put into the tribulation of threefold miseries. I do not want to die. Why death is enforced upon me? I do not want to take birth. Why that is also enforced upon me? I do not want old age. Why it is enforced upon me? I do not want disease. Why it is enforced upon me? And what is the purpose of my coming in this material world, and where I shall go after my death? Or this is the finish?" There are so many things to inquire. That is called tattva-jijñāsā. This is called tattva-jijñāsā. Jīvasya tattva-jijñāsā.
The Bhāgavata recommends that in the human form of life, the only necessity is to inquire about the Absolute Truth. That includes so many other things. The Absolute Truth is experienced by different persons from different angle of vision. That is explained here. Vadanti tat tattva-vidas tattvam (SB 1.2.11). That is the Absolute Truth—Brahman or Parabrahman—which is nondual. Vadanti tat tattva-vidas tattvaṁ yaj jñānam advayam (SB 1.2.11). Advayam means without any duality. When we say Brahman, impersonal Brahman, or when we speak Paramātmā, or when we speak of Bhagavān, the Supreme Personality of Godhead, there is no difference between these three terms. Just like sunshine and the sun globe and the sun-god. According to Bhagavad-gītā, we have got the name of the predominating deity in the sun globe. Imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). This is said in the Bhagavad-gītā. First of all Kṛṣṇa says, "Long, long ago, millions of years ago, I spoke this philosophy of Bhagavad-gītā to Vivasvān." Vivasvān means the present predominating deity of the sun globe. Just like we have got a president, similarly, but he has got a particular name, similarly, the president of the sun globe is called Sūrya, Sūryadeva. But he has got a particular name.
So at the present moment, the predominating deity of the sun globe is called Vivasvān. So this Vivasvān or the sun-god and the sun globe and the sunshine, they are not different. All of them are light. Without light in the sun globe, how so much light is emanating? So therefore the inhabitants of the sun globe, their body is made of fire. Therefore everything is glowing. And we, from distant place, we see the sun globe also glowing. And the sunshine is also glowing. Similarly, Brahman, Paramātmā and Bhagavān, they are one, the glowing or the light, but still, there is difference. What is that difference? If you remain in the sunshine... Every one of us, we remain in the sunshine. That does not mean that I am in the sun globe or I have seen the predominating deity, Vivasvān. Similarly, brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11), you can realize the Absolute Truth in three features: Brahman, Paramātmā... (break)... brahmeti paramātmeti bhagavān iti śabdyate. The same Absolute Truth is realized from three angles of vision. Those who are trying to understand the Absolute Truth by their own scholarship, eruditely... There are many philosophers. They are trying to find out what is the original source of everything. The scientists, they are also trying to find out the original source of everything. So somebody, say, for example, the scientists, they are finding original of everything as matter, chemical, chemical evolution, the modern theory of originality. But actually, if we study what is the position of chemical theory, the so-called scientists, they could not produce life from chemicals, although their theory is that from matter life comes.
This is against our Vedic knowledge. Vedic knowledge says, as it is said in the Brahma-sūtra, Vedānta-sūtra, that the original cause of the Absolute Truth is a living entity. It is not matter. Just like Kṛṣṇa says in the Bhagavad-gītā, ahaṁ sarvasya prabhavo mattaḥ sarvaṁ pravartate (BG 10.8). That aham, Kṛṣṇa, is not a dead matter. He is the living entity, supreme living entity. And we also understand from Upaniṣad, nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). The Absolute Truth is person, a living entity. He is the supreme living entity. Similarly, the original Absolute Truth is Kṛṣṇa. Kṛṣṇa says in the Bhagavad-gītā, mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7). That is Absolute Truth. There is no more para-tattva, superior tattva. Here the question is vadanti tat tattva-vidas tattvam (SB 1.2.11). We want to know the Absolute Truth. And here is Kṛṣṇa, Bhagavān. Bhagavān is the Absolute Truth, Kṛṣṇa. Bālajī is Absolute Truth, Bhagavān, person. Brahmaṇo 'haṁ pratiṣṭhā. In the Bhagavad-gītā it is said, "The impersonal Brahman is situated on Me." Just like the sunshine. Although it is all-pervading throughout the universe, the light is there, but wherefrom the light is coming? The light is coming from Kṛṣṇa.
