The Bhagavad-gita can be consulted in all critical times, not only for solace from all kinds of mental agonies, but also for the way out of great entanglements which may embarrass one in some critical hour. If one properly follows the instructions of Bhagavad-gita, one can be freed from all miseries and anxieties in this life, and one's next life will be spiritual.

By drinking the Ganges waters of the Gita, the divine quintessence of the Mahabharata emanating from the holy lotus mouth of Lord Vishnu, one will never take rebirth in the material world again. In other words, by devotionally reciting the Gita, the cycle of birth and death is terminated. (Gita-mahatmyam)

A person who studies the Gita during holy festival days especially the fasting day known as Ekadasi - such a person, whether awake or asleep, moving or still, is never defeated by enemies. Great sacrifices such as the Ashvamedha, along with their remunerations are naturally achieved by one who daily hears and recites the Gita. (Sri Vaisnaviya-tantra-sara)

Bhagavad-gita is a standard book of knowledge coming down from time immemorial. As stated by Lord Krishna Himself in the Gita, He spoke Bhagavad-gita first to the sun-god Vivasvan. According to a rough estimate, the Gita was spoken at least 120,400,000 years ago! It was again spoken by the Lord to Arjuna about five thousand years ago.

It is stated in the Gita-mahatmyam: 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.

Sri Vaisnaviya-tantra-sara mentions that there is never any suffering from the threefold miseries, nor is there ever fear of any type of sickness, curse, black rites, sin or misfortune in that house where the Gita is worshipped. In that house, no one is ever born with an infected or deformed body.

Bhagavad-gita, also called Gitopanishad, is the essence of Vedic knowledge. The study of the Vedas and Puranas - verily, the study of all scriptures is completed in all respects by one who studies the Gita with devotion.

Out of many standard and authoritative revealed scriptures, the Bhagavad-gita is the best. One will find in the Bhagavad-gita all that is contained in other scriptures, but the reader will also find things which are not to be found elsewhere. That is the specific standard of the Gita. (Srila Prabhupada)

This Gitopanisad, Bhagavad-gita, the essence of all the Upanishads, is just like a cow, and Lord Krishna, 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. (Introduction to Bhagavad-gita As It Is)
