Bhagavatam : (B.Gita as it is 4.16 purport)Easy way to achieve perfection (1 minute video)By mental speculation one cannot ascertain what is religion or self-realization. Therefore, out of causeless mercy to His devotees, the Lord explains directly to Arjuna what action is and what inaction is.It is said that one cannot ascertain the ways of religion simply by imperfect experimental knowledge. Actually, the principles of religion can only be laid down by the Lord Himself. Dharmaḿ tu sākṣād bhagavat-praṇītam (Bhāgavatam 6.3.19). No one can manufacture a religious principle by imperfect speculation. One must follow in the footsteps of great authorities like Brahmā, Śiva, Nārada, Manu, the Kumāras, Kapila, Prahlāda, Bhīṣma, Śukadeva Gosvāmī, Yamarāja, Janaka, and Bali Mahārāja.Only action performed in Kṛṣṇa consciousness can deliver a person from the entanglement of material existence.
