There are other major traditions of Buddhism, called Mahayana and Vajrayana, and these traditions put no limits on the number of buddhas there can be. However, for practitioners of Mahayana and Vajrayana Buddhism the ideal is to be a bodhisattva, one who vows to remain in the world until all beings are enlightened.
There are multitudes of buddhas, especially in Mahayana and Vajrayana scriptures and art. They represent aspects of enlightenment, and they also represent our own deepest natures. Some of the better known iconic or transcendent buddhas include Amitabha, the Buddha of Boundless Light; Bhaiṣajyaguru, the Medicine Buddha who represents the power of healing; and Vairocana, the universal or primordial Buddha who represents absolute reality. The way the buddhas are posed also convey particular meanings.
Enlightenment is also described as perceiving buddhanature, which in Vajrayana and Mahayana Buddhism is the fundamental nature of all beings. One way to understand this is to say that the enlightenment of the Buddha is always present, whether we are aware of it or not.
Tibetan Buddhists use specialized meditation techniques to visualize themselves as peaceful or wrathful buddhas, depending on the state of mind they are trying to achieve. Practitioners learn these techniques through initiations, which may involve cards painted with images of body parts, ornaments and offerings, such as the one pictured. 041b061a72
