At the beginning, you need to persevere, slowly find the correct practice method of yoga, develop accurately, and get better in all aspects of body and mind. However, the more you practice, the more focused you will be, the more interested you will be, and you will become a lover of communication. After a long time, the yoga master will naturally come out and become a good teacher. If two hours a day are uninterrupted for at least four years, four hours is almost the same as two years. About 3000 hours of practice. Of course, more than 4 hours and less than 1.5 hours is of little significance. The former is overworked and the latter is ineffective. Iyengar said it's not just a matter of time. In the early days, this muscle didn't work, and that muscle didn't listen. Now my cells will talk to me, and my heart will talk to me. I feel my energy, my heart, my intellectual movement. I am not only observing, I am also with myself, and I am there. Now you may not understand that as you gradually practice, maybe one day the light of enlightenment will illuminate you.
