Paramahansa Yogananda (Bengali: পরমহংস যোগানন্দ Pôromohôngsho Joganondo, Sanskrit: परमहंस योगानंद Paramahaṃsa Yogānaṃda), born Mukunda Lal Ghosh (Bengali: মুকুন্দ লাল ঘোষ Mukundo Lal Ghosh), was an Indian yogi and guru who introduced many westerners to the teachings of meditation and Kriya Yoga through his book, Autobiography of a Yogi.
If you can manage that is very clearly written from a different age, and has some fairly ableist language, then yeah, I could see it being helpful on a spiritual journey. I do like the structure by which it describes how to practice affirmations but the affirmations it provides would be a bit bulky to practice as they are.
