Final answer:
Tantric or Tibetan Buddhism is a branch of Buddhism distinctive for its esoteric rituals and practices, set apart from Theravada's meditation focus and Mahayana's universal compassion.
Step-by-step explanation:
Tantric Buddhism, often referred to as Tibetan Buddhism or Vajrayana Buddhism, is the northern tradition of Buddhism primarily found in Tibet, Western China, Bhutan, Nepal, and parts of Mongolia.
This branch is rooted in the teachings of the Buddha and places a strong emphasis on meditation as well as spiritual techniques to break the cycle of birth, death, and rebirth.
Vajrayana Buddhism is viewed by some as a part of the larger Mahayana Buddhist tradition which also includes varieties such as Zen Buddhism and other forms of East Asian Buddhism.
One of the key differences between Tibetan Buddhism and the other branches is its esoteric nature, harnessing rituals, mantras, and mystical practices that distinguish it from the more orthodox and meditation-centered Theravada Buddhism as well as from Mahayana's compassion and altruism-focused practices.
Another significant form of Buddhism is Theravada Buddhism, which seeks to adhere closely to the original teachings of the Buddha, is found in Southeast Asia and Sri Lanka, and emphasizes individual enlightenment through meditation.
Mahayana Buddhism, found in countries like Japan, Taiwan, Korea, and Eastern China, places greater emphasis on the bodhisattva path, aiming for the enlightenment of all beings and featuring a diversity of practices and philosophical approaches.
Overall, despite the variety of traditional expressions, all branches of Buddhism reject caste systems and share a common goal of attaining liberation from suffering.
