The Maitreya Buddha
The Buddha Maitreya (Tibetan: Jetsun Jampa Gonpo) Is a Mahābodhisattva
who would be the next Buddha to come when teaching the Buddha Sakyamuni, will have disappeared.
Belief in the advent of Maitreya is common
to theravāda and mahāyāna schools of Buddhism.
In the distant future (about 5000 years after the Parinirvana of Buddha Sakyamuni), when the Buddhist teachings are extinguished,
the Buddha Maitreya will incarnate to teach again
the Holy Dharma.
The Most Holy Nagarjuna describes the devotion towards Maitreya
as an easy way to enlightenment.
Buddha Maitreya is known as a protector of beings,
wearing an amulet in his image is a powerful safeguard
against the vagaries of material life and gives a physical connection
with the Buddha of the future.
