I am a yoga instructor. I do hatha yoga and raja which are well known types.
I don't know much about yoga. What are the benefits?
Well it became popular in the 1980s as a from of physical exercise. Also great for the mental state.
I heard it is good for relaxation. What is the difference between hatha and raja?
Hatha emphasizes exercise to master the body and withdraw it from objects.
Oh that sounds cool.
Yes, yoga in Indian traditions are more than physical exercise. It has meditative and spiritual cores.
