One can sleep lesser and deeper, feel energetic, happier, and so much love for everybody with the practice of yoga. What more do you want?
First of all, remove this idea from your mind, ‘Oh, nobody is motivated, nobody comes’, you should not have this thought in your mind. You must know you have something that everybody wants and needs, and they will come.
In our mind if we think, ‘Oh, nobody is motivated, nobody wants to come’, then nobody comes. Every day new yoga centers are opening in Tokyo that means people want it.
