“Sangha is crucial. If you are without a sangha you lose your practice very soon. In our tradition we say that without the Sangha you are like a tiger that has left his mountain and gone to the lowlands – he will be caught and killed by humans. If you practice without a Sangha you are abandoning your practice.” – Thich Nhat Hanh
The Buddha said of the three refuges the Sangha was the most important.
