Theravada Tradition emphasizes meditation on the breath to cultivate concentration and meditation on the body, feelings, mind and phenomena to develop wisdom. Mahayana has subdivisions: Pure Land, Zen, Vajrayana, etc. Pure Land Tradition emphasizes chanting the name of Amitabha Buddha in order to be reborn into his Pure Land - a place where all conditions are conducive to Dharma practice. Zen Tradition - emphasizes meditation and chanting to eliminate the noisy conceptual mind.
All Buddhist Traditions emphasize meditation and chanting to lesson the suffering in the world and to cultivate qualities such as compassion, joy, generosity, lovingkindness, and wisdom.
They all have the same goal.
