[QUOTE=Sarvamaṅgalamaṅgalā;62692]Computers are build on a certain set of scientific principles, not on American culture. Likewise, yoga is build on certain metaphysical principles of Hinduism. Of course, any religion is free to adopt them, but that would change the nature of those other religions completely.
It is not an integral part of their system. Someone could also play a computer game and then do their Christian, muslim prayers to save their souls. That doesn’t change anything in the nature of computer games. Of course, anyone can engage in the practice of yoga, but that doesn’t change the fact that yoga is grounded in Hindu thought.[/QUOTE]
Perhaps you forget that religions have an exoteric and an esoteric face.
Exoteric for believers, esoteric for seekers.
What you say might be true for the former, who cling to dogmas and shut many doors, but no for the later, who remain open and use anything may help them to evolve.
In fact, aren’t there tantric muslim fakirs there in India?
