How did the concept of the Three Dharma Seals originate? According to the sutras, when Sakyamuni Buddha was about to enter parinirvana, a disciple asked the Buddha, “If a non- Buddhist or some other person comes along after you are gone to give teachings and proclaims that to be the Dharma, how should we discern if it is the true Dharma?” The Buddha replied, “After I am gone, any belief or teaching which incorporates the Three Dharma Seals is the true Dharma; any belief or teaching which not only excludes but also refutes the Three Dharma Seals is not the true Dharma.”
