In the present age, people are so absorbed in mundane activities that it is not possible for them to read all the Vedic literatures. But this is not necessary. This one book, Bhagavad-gītā, will suffice, because it is the essence of all Vedic literatures and especially because it is spoken by the Supreme Personality of Godhead. (Gītā-māhātmya 4)
As it is said:
- bhāratāmṛta-sarvasvaṁ
- viṣṇu-vaktrād viniḥsṛtam
- gītā-gaṅgodakaṁ pītvā
- punar janma na vidyate
"One who drinks the water of the Ganges attains salvation, so what to speak of one who drinks the nectar of Bhagavad-gītā? Bhagavad-gītā is the essential nectar of the Mahābhārata, and it is spoken by Lord Kṛṣṇa Himself, the original Viṣṇu." (Gītā-māhātmya 5) Bhagavad-gītā comes from the mouth of the Supreme Personality of Godhead, and the Ganges is said to emanate from the lotus feet of the Lord. Of course, there is no difference between the mouth and the feet of the Supreme Lord, but from an impartial study we can appreciate that Bhagavad-gītā is even more important than the water of the Ganges.
