The laity are very important in Buddhism, for they are the supporting members of the Buddhist community. They build the temples and monasteries and give offerings of food, robes, bedding, and medicine to the monks and nuns. This enables the Sangha to carry on the Buddha's work. In this way the Sangha and laity benefit each other and together keep the Dharma alive.
In Buddhism, it is also important to support the poor and needy. Giving to support religious people, however, is considered a very meritorious deed. The Buddha not only encouraged giving to Buddhists, but to any spiritual person who is sincere.
The Buddha taught his disciples to be tolerant of other religions. For example, when one lights a candle from the flame of another candle, the flame of the first candle does not lose its light. Instead, the two lights glow more brightly together. It is the same with the great religions of the world.
Whether one is a member of the Sangha or a lay person, the ideal is to practice Buddhism for the sake of all.
