thank you @distantsignal. Really? you think so?. Some people close their chakras and they believe that this prevents negative energy from getting in and prevents them from being influenced by religious believes or entities that suck your energy. But, yoga is an ancient practice with much complexity. It is not for everyone but everyone can use it. I think it all comes down to what a person believes in. yoga is not a modern practice, its a way of thinking at the universe, a way of expression of your imagination.
