How does the spiritual practice of yoga differ from the kind of yoga most gyms/clubs

[L'amour est le chaos]

teach? I heard before that most only give very basic stretching but real yoga has a lot more to it. I was just wondering what that is all about exactly. Is it more complex moves or is there a specific spiritual implication?

Im not sure about the details, but anyone should stay away from it, its an occult practice and is a doorway for evil spirits and it is very dangerous.
