In self defence we do not aim to become nasty and cruel. Simply escape. Do only what is necessary.

Many kung fu students have a very balanced relationship with the world around them; animals, environment and people.
They refrain from hurting other people with words, actions or deeds.
Often, they are vegetarian and actively work to encourage other people to respect all life.

We can learn a lot from animals and can repay these lessons with kindness and compassion.
