Find your own way to practice yoga. Take the best for you and accept in any yoga class the things that are personally not effective for you. And above all, always stay on your path of truth and accuracy. Don´t give up your mind on the door to spirituality. Many people exercise wrong. They practice yoga only formally (as an external form) without inner feeling. They do not resolve tensions. It is important that we practice goal-oriented, effective and with endurance.
