Books are a second teacher if the Master is unavailable
Books of realised Masters
Read the books of realised Masters, talk to people who are walking the path and have personal experience, converse with the Masters, do not waste time on empty communication with those who do not know anything about it.
I advise you to start with Paramahansa Yogananda’s Autobiography of a yogi or to read Yukteswar Giri’s Holy Science or any book that talks about Kriya yoga.
Many people were inspired by the wonderful work The Yoga of Siddha Boganathar or Babaji and the 18 Siddha Kriya Yoga Tradition by Marshall Govindan, as well as the books by Svyatoslav Dubyanskiy, who tries to preserve the accuracy of information transmission.
The books of Yogananda and Sathya Sai Baba possess certain vibrations, energy and information. A person who reads these books thus becomes inspired.
Of course, a book cannot convey the spiritual powers that a person receives during Kriya practice and when conversing with a Master.
Therefore, individual sadhana and group work is very valuable, since Babaji shows his Holy Presence wherever five practise Kriya…
Whenever talking about Kriya yoga, we recommend all the books by the realised Master Paramahansa Yogananda.
There are several other spiritual leaders currently living in the modern world, and you can choose them too. The books by Sri Aurobindo and all the books and lectures by Sathya Sai Baba. Since Sai Baba is the incarnated Purna Avatar, He delivered knowledge in a way that people could understand very easily.
There are so many yoga sutras, starting with the Kriya Siddha of Patanjali and ending with all the other sutras.
The criterion of truth
I have not read these books, but I am connected to them. I didn’t read, I didn’t sit, I didn’t waste time but focused on internal work.
When I say Kriya, you shouldn’t feel that I am trying to fit all the systems and directions into this little word — Kriya, as a system of some yogic Indian principle.
Kriya is not an Indian style or denomination. The Kriya Babaji method has been given to the whole world as a Single Universal Method, as a non-religious path to the Cosmic Consciousness! This is Cosmic Law, in action… When Kriya arose, Hinduism did not yet exist).
Books are helpers, but if you know — do not ask, but Act! Reach your Goal!
