Atma-Siddhi is a scripture, a sacred book. So also its author Shrimad Rajchandra is one of the adored, holy, true spiritual Masters, the world has ever known. His embodied life was comparitively very short. He was born in 1868 A.D. in a place known as Vavania in Gujrat (INDIA) and died at the age of 33. During this short span of life, he saw the Truth face to face and taught the Truth to his blessed worshippers, one of whom was Mahatma Gandhi. Few people know that the man of the greatness of Mahatma Gandhi was so captivated in spiritual and religious matters by this seer of Truth as by no other man. Mahatma Gandhi came in contact with many religious heads. He tried to meet Heads of each religion, but none could create the impression on him which Shrimad Rajchandra did. His influence on Mahatma Gandhi was deeper than even that of  Tolstoy and Ruskin. That is why it is said that the writings of Shrimad Rajchandra , mostly in letters , help a good deal in understanding correctly what Mahatma Gandhi stood for and preached on the spiritual and religious side. 

A respectable, honest businessman in outward life, his inner life was of a Saint. He was a partner in a firm dealing in gems. He knew his job very well as a jeweller and carried the burden of big business operations in India as well as outside. There was a rare combination of right businessmanship with true religion in him. He disproved the notion of the business world that a successful businessman cannot remain strictly ethical. He was a real follower of Jina, who conquered passion of attachment, aversion and ignorance and attained absolute purity and perfection. He never gave importance to caste or creed of birth in the path of liberation. He had true experience, knowledge and belief of self, distinct from the embodied existence and his concious attentiveness was found eager to flow in the self, even in the midst of big business transactions. 

He had an extraordinary memory. His mind was able to function in hundred directions at a time. He was therefore known as Shatavadhani. He had good control over words, both in speech and writing. It is said that he hardly scored what he wrote. He had always at his command the right word at the right place. Every  word and every action of his had the mark of his greatness, poise, dignity, character, discipline, and earnest striving for liberation and perfection of soul. Though not known to the other parts of the world, he was unique, a mass of many pure states of qualities in human body, actually living on the face of the earth. He was an Atma-Gnani, a knower of self, and his state of existence was without attachment for a position, wealth, fame and even the body, though in embodied condition.
