In summary it should be understood that all these materialistic philosophers have tried to avoid the Supreme Personality of Godhead by putting forward their own mentally concocted philosophies. However, Vyāsadeva, the great sage and incarnation of Godhead, has thoroughly studied all these philosophical speculations and in answer has compiled the Vedānta-sūtra, which establishes the relationship between the living entity and the Supreme Personality of Godhead and the importance of devotional service in ultimately achieving love of Godhead. The verse janmādy asya yataḥ (SB 1.1.1), which appears in the very beginning of Vedānta-sūtra, is explained in Vyāsadeva's Śrīmad-Bhāgavatam. In Śrīmad-Bhāgavatam Vyāsadeva establishes from the very beginning that the supreme source of everything is a cognizant, transcendental person.
The impersonalist tries to explain that the impersonal effulgence of the Supreme Lord (brahmajyoti) is beyond these material modes of nature, but at the same time he tries to establish that the Supreme Personality of Godhead is contaminated by the modes of material nature. The Vedānta-sūtra asserts that the Supreme Personality of Godhead is not only transcendental to the material modes of nature but that He also has innumerable transcendental qualities and energies. All these various speculative philosophers are one in denying the existence of the Supreme Lord Viṣṇu, and they are very much enthused to propagate their own theories and be recognized by the people. Unfortunate people become enamored of these atheistic philosophers and consequently can never understand the real nature of the Absolute Truth. It is far better to follow in the footsteps of great souls (mahājanas). According to Śrīmad-Bhāgavatam, there are twelve mahājanas, or great souls, and these are: (1) Brahmā, (2) Lord Śiva, (3) Nārada, (4) Vaivasvata Manu, (5) Kapila (not the atheist, but the original Kapila), (6) the Kumāras, (7) Prahlāda, (8) Bhīṣma, (9) Janaka, (10) Bali, (11) Śukadeva Gosvāmī and (12) Yamarāja. According to the Mahābhārata, there is no point in arguing about the Absolute Truth because there are so many different Vedic scriptures and philosophical understandings that no one philosopher can agree with another. Since everyone is trying to present his own point of view and reject others, it is very difficult to understand the necessity for religious principles. Therefore it is better to follow in the footsteps of the great mahājanas, great souls; then one can achieve the desired success. Lord Caitanya's teachings are just like nectar, and they hold whatever is needed. The best way is to take to this path and follow it.
