Yoga is about establishing character in people's hearts. Real character is the willingness to make personal sacrifices for a higher ideal, willingness to embrace those ideals that we hold sacred even in the face of temptation or fear. Yoga is meant to bring about from within our whole hearts genuine compassion for the well-being of other living beings. This is the greatest need in human society. There's a law of economics, an environmental law of economics that what we take we must return and what we return is what is going to come back to us. So, we are taking so much good from Mother Earth and we are returning with toxic waste. And therefore, eventually what is returned is toxic poison to us. We must take responsibility.
