All the great spiritual leaders in western Vedic viewpoint have acknowledged Krishna while the Great Character of Godhead, Bhagavan. Among them are the famous Acaryas (those who lead by example) like Sankaracarya, Ramanujacarya, Madhavacarya, Nimbarka Swami and Caitanya Mahaprabhu.
Also, in the Bhagavad Gita, Krishna also places Himself forward as the Great Character of Godhead. In fact, there's been no different character present on earth in history who has stated herself while the Supreme Personality of Godhead. Thus, the final outcome is that the Bhagavad Gita must be taken as focused by the Great Personality of Godhead Himself, Krishna.
Krishna shows Arjuna (and all of us) that the yoga program, Bhagavad Gita, includes a long and serious history. He first spoke it to the sun-god, who then talked it to his son, and in this way it continued to come down through the ages from instructor to student. In the fourth chapter of the Gita, it's explained that the Gita was initially talked about 120,400,000 years ago, and that it has been in individual society for 2
years. As time passed, the Gita did actually become missing and this is actually the reason that Krishna gives for having to again speak it to Arjuna.
Arjuna wasn't an ordinary common person, he was highly competent as a military man, and is really a recorded character in the backgrounds of India.
Even though extant in individual culture for just two million decades, the Bhagavad Gita was written down 5000 decades ago. Although there have been a few hundred types of the Gita presented within the last centruy, they certainly were mostly written by experts have been outside the disciplic succession from Krishna, and thence they offered a "clouded" misinterpretation of the actual message.
Fortunately, His Divine Acceptance A C Bhaktivedanta Swami Prabhupada, under the get of his spiritual grasp, wrote an authorized variation of the Gita for the benefit of all souls that are critical to know the information of the Gita. He's individually qualified to provide the meaning in it's original form without any model or speculation, as is distinct in his Bhagavad Gita named "As It Is" ;.
