So we have to understand the philosophy through the sampradāya. Sampradāya-vihīnā ye mantrās te niṣphalā matāḥ. If you don't accept... In ordinary life also, in political field, to develop, one has to accept a party, this party or that Congress Party, or Jana-sanga Party, or this party. So the aim is the same. Aim is the same, to serve the country, to develop your country, but still, there are parties. Similarly, the aim is the same: to understand what is our relationship with God. But the development is made by different parties. So the parties are, must be bona fide. As Kṛṣṇa says, His party:
- imaṁ vivasvate yogaṁ
- proktavān aham avyayam
- vivasvān manave prāha
- manur ikṣvākave 'bravīt
- (BG 4.1)
- evaṁ paramparā-prāptam
- imaṁ rājarṣayo viduḥ
- (BG 4.2)
Kṛṣṇa said that "First of all, I described, I instructed this yoga system, bhakti-yoga system, Bhagavad-gītā, to Vivasvān, the sun-god, and the sun-god, whose name is Vivasvān..." The particular name is also given. It is not vague, that... At the present moment, the predominating Deity in the sun planet is called Vivasvān. So he spoke this Bhagavad-gītā philosophy to his son, vivasvān manave prā..., Manu. Manu is the original person of the human society. Manuṣya. Man. So Manu spoke to his son, Ikṣvāku. Mahārāja Ikṣvāku. He's the first person of the sūrya-vaṁśa. There are two kṣatriya families: one, candra-vaṁśa, coming from the Moon, and the other from the Sun, Vivasvān. So Mahārāja Ikṣvāku is the original personality in the sūrya-vaṁśa kṣatriyas in which Lord Rāmacandra appeared. So in this way, there is paramparā system.
