The original commentary of Adi Shankaracharya on Bhagavad Gita is available in Sanskrit from Gita press, Gorakhpur, India. Anything written by Adi Shankaracharya is invaluable. Adi Shankaracharyas contribution to society in a limited life span of 32 years is overwhelming. At the young age of 15… He completed his commentary on Bhagavad Gita.
Adi Shankaracharya is famously remembered for his doctrine of Advaita Vedanta. Adi Shankaracharya vociferously advocated that Brahman (God Almighty) was the only truth of life. God was one and only one. He also propagated doctrine of Maya (veil of ignorance) according to which it was proved beyond doubt that other than God Almighty nothing existed in cosmos.
Adi Shankaracharya apart from commentary on Bhagavad Gita also wrote extensively on Vedas, Brahma sutras and Upanishads (independent treatises). But all his works are in Sanskrit language which is an impediment for today’s society. However those who had some knowledge of Sanskrit can definitely go through his commentary on Bhagavad Gita, Brahma sutras and Upanishads.
It was Adi Shankaracharya who firmly established in spiritual circles that doctrine of Advaita Vedanta was irrefutable proof of existence of God Almighty in cosmic system. Reading his thoughts on doctrine of Maya (veil of ignorance) is truly an eye-opener. One who had absolute faith in God Almighty can surely understand teachings of Adi Shankaracharya in totality.
Mastering Vedas… writing commentary on Bhagavad Gita, Brahma sutras and Upanishads (independent treatises) was something that none before Adi Shankaracharya succeeded in doing. Even though Adi Shankaracharya was a firm believer of Vedas (Hinduism revelations)… he was also a follower of path of jnana yoga (path of absolute wisdom).
His catch of spiritual principles of life was extraordinary. He achieved most even before reaching 20 years of age. This fact made him the spiritual master of his times. The doctrines put forward by Adi Shankaracharya… the logical conclusions proved beyond doubt that he was truly a spiritual genius. Adi Sankara believed in Nirakaar form of God (having no form).
Adi Sankara was a perfect Jnana Yogi… a perfect karma yogi who firmly believed in concept of nishkama karma yoga. Adi Shankaracharya frequently indulged in discourses… debates with like-minded people. His logical thinking finally made him win the end. Adi Shankaracharya was considered one of the greatest thinkers of his times… so much so that none could ever defeat him in extempore debates… discourses!
