…It was shortly after that [Master’s great samadhi of 1948] that [Paramahansaji] said, “I have to give time now to my writings. Divine Mother didn’t take me…I still have some work to do.” He knew that God was calling him to greater seclusion. So in his little desert retreat, when he could tear himself away from Encinitas and Mt. Washington activities — after ’48 he didn’t speak regularly as he had always done…and he began to spend then more time at the desert. He used to say… “I can do much more now to reach others with my pen.” He didn’t have the time anymore to just give one-on-one interviews.
So his whole consciousness became absorbed in finishing what he felt Divine Mother wanted him to finish in the way of his writings. He went over the Lessons, he went over many of the previously published articles and items. He worked with Tara Ma, I know, on the Whispers. And he dictated to all of us, we all took a turn typing and he would dictate on his manuscripts.
And he would be totally, totally lost, totally absorbed — hours would go by. And we would have to remind him, “Master, you have been sitting so many hours. Shouldn’t you take some food, shouldn’t you take a break? And usually he would say, “No, my consciousness is in it. I have to finish. I have to finish.”
Paramahansa Yogananda’s final years were spent largely in seclusion, as he labored intensely to complete his writings — including his voluminous commentaries on the Bhagavad Gita and the teachings of Jesus Christ in the four Gospels, and revisions of earlier works such as Whispers from Eternity and the Self-Realization Fellowship Lessons. He also worked extensively with Sri Daya Mata, Mrinalini Mata, and a few other of his closest disciples, imparting the spiritual and organizational guidance that would enable them to carry on his worldwide work after he would be gone. ….
In accord with [Paramahansaji’s] express wishes, Self-Realization Fellowship has continued the ongoing task of publishing and keeping permanently in print The Complete Works of Paramahansa Yogananda. These include not only the final editions of all the books he published during his lifetime, but also many new titles — works that had remained unpublished at the time of his passing in 1952, or which had been serialized over the years in incomplete form in Self-Realization Fellowship’s magazine, as well as hundreds of profoundly inspiring lectures and informal talks recorded but not printed before his passing…
Self-Realization Fellowship’s editions, and none others, incorporate all of the author’s wishes for the final text of Autobiography of a Yogi…Readers of Autobiography of a Yogi sometimes inquire about the differences between the current edition and the first edition published in 1946.
Three editions of Paramahansaji’s autobiography appeared during his lifetime…the third edition [was] published in 1951…Some further revisions made by him after the third edition could not be incorporated until the publication of the seventh edition, which was released in 1956…
