Baghavat Gita is the essence of all Hindu Scriptures. It was told by Lord Krsna to Arjuna on the battle field of Kuruksetra.

Bhagavat Gita deals mainly with five subject matters

Isvarah - who is the Supreme Person, the cause of all causes and what are his activities and qualities

Jiva - who is a living entity and what is his nature

Prakriti - material nature, what is it made of, its purpose and how does it function

Kala - time factor and

Karma - activities carried out in this material world.


The conclusion is that Bhagavad-gita is a transcendental literature which one should read very carefully. If one properly follows the instructions of Bhagavad-gita, one can be freed from all the miseries and anxieties of life. One will be freed from all fears in this life, and in one's next life one will attain the spiritual world.
(Gita-Mahatmiya 1)
If one reads Bhagavad-gita very sincerely and with all seriousness, then by the grace of the Lord the reactions of his past misdeeds will not act upon him.
(Gita-Mahatmiya 2)


One may cleanse himself daily by taking a bath in water, but if one takes a bath even once in the sacred Ganges water of Bhagavad-gita, for him the dirt of material life is altogether vanquished.
(Gita-Mahatmiya 3)


Because Bhagavad-Gita 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-Gita. 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-Gita, will suffice, because it is the essence of all Vedic literatures and especially because it is spoken by the Supreme Personality of Godhead.
(Gita-Mahatmiya 4)


One who drinks the water of the Ganges attains salvation, so what to speak of one who drinks the nectar of Bhagavad-gita? Bhagavad-gita is the essential nectar of the Mahabharata, and it is spoken by Lord Krsna Himself, the original Visnu.
(Gita-Mahatmya 5)


This Gitopanisad, Bhagavad-gita, the essence of all the Upanisads, is just like a cow, and Lord Krsna, who is famous as a cowherd boy, is milking this cow. Arjuna is just like a calf, and learned scholars and pure devotees are to drink the nectarean milk of Bhagavad-gita.
(Gita-Mahatmya 6)


In this present day, people are very much eager to have one scripture, one God, one religion, and one occupation. Therefore, ekam sastram devaki-putra-gitam: let there be one scripture only, one common scripture for the whole world--Bhagavad-gita. Eko devo devaki-putra eva: let there be one God for the whole world--Sri Krsna. Eko mantras tasya namani: and one hymn, one mantra, one prayer--the chanting of His name:

Karmapy ekam tasya devasya seva: and let there be one work only--the service of the Supreme Personality of Godhead.
(Gita-Mahatmya 7)
