Love everyone, including yourself. This is real sadhana.
If you work on yoga, yoga will work on you.
You can't teach a hunter it's wrong to kill.
When body, breath, and mind work together in harmony to achieve a spiritual goal, that is yoga.
Cultivate a sympathetic heart, humility in dealings, and selflessness in action. If these are practiced with earnestness and sincerity, then you will win the race of life.
No one can please everyone. Your mental peace is more important. If you are in peace, then others around you will feel peace. So your best effort should be to work on yourself.
