To change with change is the changeless state

Cease negative mental chattering. If you think a thing is impossible, you'll make it impossible. Pessimism blunts the tools you need to succeed.

There’s only one basic principle of self-defense- you must apply the most effective weapon, as soon as possible, to the most vulnerable target.

Ultimately the greatest help is self-help.

To tell the truth, I could beat anybody in the world.

One must be truthful and honest in his approach; a constant independent inquiry and not blindly following a certain blue print laid down by others

Have no rigid system in you, and you'll be flexible to change with the ever changing.
