ok! prasad means, gods blessed food, it's like they cook some food, offer it 2 god and then eat it.
morevr talking abt bhakthiyoga, actually yoga emerged from Hindu monks, actually they used to go meditate for years at a time, to keep themselves healthy they started doing yoga, that's it.
actually Hinduism was practiced since the early man cultures, there's one in India called harappan culture, it's like the first ever colonies of prehistoric times, they proved that they prayed sun god(one of Hindus gods).
