As it is said that one who drinks the water of the Ganges, he also gets salvation, then what to speak of Bhagavad-gītā? Bhagavad-gītā is the nectar in the whole Mahābhārata, and is spoken by Viṣṇu. Lord Kṛṣṇa is the original Viṣṇu. Viṣṇu-vaktrād viniḥsṛtam. It is coming out of the mouth of the Supreme Personality of Godhead. And gaṅgodakaṁ, the Ganges is said to be emanated from the lotus feet of the Lord, and Bhagavad-gītā is emanated from the mouth of the Lord. Of course, there is no difference between the mouth and the feet of the Supreme Lord. Still, from neutral position we can study that Bhagavad-gītā is even more important than the Ganges water.
