Yogananda is credited with bringing the teachings of meditation and Kriya Yoga to Western audiences. He arrived in the United States in 1920 and established the Self-Realization Fellowship (SRF) to spread his message.

His primary teaching was Kriya Yoga, a spiritual practice designed to accelerate spiritual growth through meditation and energy control, focusing on breath and inner stillness.

He was known for his captivating speaking style and deep spiritual presence, delivering lectures across the U.S., including a cross-country speaking tour in the 1920s and 1930s.

Yogananda stressed the importance of healthy living, introducing yogic practices, diet, and exercise to promote physical well-being in connection with spiritual growth.
