Sirsasana the king of all asanas and the reasons are not hard to find.

Do not allow past experiences to be imprinted on your mind. Perform asanas each time with a fresh mind and with a fresh approach. If you are repeating what you did before, you are living in the memory, so you are living in the past. That means you don't want to proceed beyond the experience of the past. Retaining that memory is saying, 'Yesterday I did it like that.' When I ask, 'Is there anything new from what I did yesterday?' then there is progress. Am I going forward or am I going backward? Then you understand how to create dynamism in a static asana.

The highest point of yesterday should be the lowest point of today

If everyone practiced yoga, pharmacies would have to close.

When you inhale, you are taking the strength from God. When you exhale, it represents the service you are giving to the world.

Do not stop trying just because perfection eludes you.

Yoga, an ancient but perfect science, deals with the evolution of humanity. This evolution includes all aspects of one's being, from bodily health to self realization. Yoga means union - the union of body with consciousness and consciousness with the soul. Yoga cultivates the ways of maintaining a balanced attitude in day to day life and endows skill in the performance of one's actions.
