Three things cannot be long
and the truth.
The idea behind taking refuge is in life we like to find a shelter. The Buddhist shelter from the problem and pain of life is threefold: the Buddha, his teachings (the Dharma) and the spiritual community (the Sangha).
Buddha means enlightened, awakened or omniscient One. A Buddha is a person who has purified all defilements and developed all good qualities.
The Sangha, are a community of travellers on the same spiritual path, who need help of with the correct way and good advice. They are our spiritual friends who can help us stay on the right path and can share their own experience..
REFUGE VOWS If we decide to go for refuge in the three jewels, we should then commit ourselves to the path we choose by respecting vows, as follows:
1 - Not killing: refers to humans and animals, it is both harming sentient beings.
