2.8
Bhagavad-ਯੁੱਖਾ  As Jt ls
2.40) If one reads  Bhagavad-gītā  sincerely and seriously, then all of the reactions of his past misdeeds will not react upon him. In the last portion of  Bhagavad-gītā , Lord Śrī Krsna proclaims:
sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja ahaṁ tvāṁ sarva-pāpebhyo moksayisvāmi mā śucah
“Give up all varieties of religiousness, and just surrender unto Me; and in return I shall protect you from all sinful reactions. Therefore, you have nothing to fear.” (Bg. 18.66) Thus the Lord takes all responsibility for one who surrenders unto Him, and He indemnifies all the reactions of sin.
One cleanses himself daily by taking a bath in water, but one who takes his bath only once in the sacred Ganges water of the  Bhagavad-gītā  cleanses away all the dirt of material life. Because  Bhagavad-gītā  is spoken by the Supreme Personality of Godhead, one need not read any other Vedic literature. One need only attentively and regularly hear and read  Bhagavad-gītā . In the present age, mankind is so absorbed with mundane activities that it is not possible to read all of 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 because it is spoken by the Supreme Personality of Godhead. It is said that one who drinks the water of the Ganges certainly gets salvation, but what to speak of one who drinks the waters of  Bhagavad-gītā ?  Gītā  is the very nectar of the  Mahābhārata  spoken by Viṣṇu Himself, for Lord Kṛṣṇa is the original Viṣṇu. It is nectar emanating from the mouth of the Supreme Personality of Godhead, and the Ganges is said to be emanating from the lotus feet of the Lord. Of course there is no difference between the mouth and the feet of the Supreme Lord, but in our position we can appreciate that the  Bhagavad-gītā  is even more important than the Ganges.
The  Bhagavad-gītā  is just like a cow, and Lord Kṛṣṇa, who is a cowherd boy, is milking this cow. The milk is the essence of the  Vedas , and Arjuna is just like a calf. The wise men, the great sages and pure devotees, are to drink the nectarean milk of  Bhagavad-gītā .
In this present day, man is very eager to have one scripture, one God, one religion, and one occupation. So let there be one common scripture for the whole world— Bhagavad-gītā . And let there be one God only for the whole world—Śrī Kṛṣṇa. And one  mantra  only—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. And let there be one work only—the service of the Supreme Personality of Godhead.
