Yoga divorced from its Hindu roots is nothing. Unfortunately, Hindu yogis sell this concoction to increase its marketability. Even greats like Paramahansa Yogananda we're not immune from this - even though I am a small person to critique them. I am always shocked when I visit their ashrams and see the level of christist infiltration.
The picture is a sign post outside the "chapel" in the Ashram founded by Paramahansa Yogananda in Encinitas, California. No further elaboration is needed.
