Himalayan Yoga does not prescribe beliefs, and there are no commandments. Instead, Yoga provides practices that lead one to the direct experience of Divinity—the experience from which all religions were born.
One might argue, “well, aren’t the Yamas and Niyamas commandments?” No, the Yamas and Niyamas are practices necessary to calm the mind and emotions so that one can reach the goal of Yoga.
So, there is not a conflict between Yoga and religion. One can practice whatever religion s/he prefers and also practice Yoga.
In fact, Swami Veda Bharati often advised people to practice their religion. He said that practicing Yoga would deepen one’s understanding of their religion. That’s my experience.
