Literature
What I read and what made the biggest impression on me.
In my personal view, the best work is the Bhagavad Gita. I read the translation by B. Grebenshchikov.
The Gospel. Here I want to point out three chapters that I personally liked most. Chapters 5, 6, and 7 of Matthew, the Sermon on the Mount.
Autobiography of a Yogi by Paramahansa Yogananda.
The Holy Science by Sri Yukteswar.
