zambala encompasses all of Buddha families. The five forms of zambala have vowed before the Buddha to liberate all sentient beings and protect the dharma. zambala is the Bodhisattva of wealth and prosperity, providing freedom from the suffering of poverty so that one can focus on the path of spirituality rather than a materialistic focus. If we have obstacles to prosperity making an offering with a sincere heart and without selfishness, thinking that all sentient beings can have wealth, and even what you receive you will share freely. One then accumulates the causes for happiness, obtains good fortune, and receives uncountable benefits. zambala also can transform obstacles and failures into success very quickly.
