Full context:   The esoteric traditions in Buddhism generally teach four chakras. In some Buddhist tantric sources, these chakras are identified as: manipura (navel), anahata (heart), vishuddha (throat) and ushnisha kamala (crown). In one development within the Nyingma lineage of the Mantrayana of Tibetan Buddhism, a popular conceptualization of chakras emerged, arranged in increasing subtlety and order. The names of the four basic Buddhist cakras are derived from the four kayas (bodies of the Buddha): nirmana (genitals), sambhoga (throat), dharmakaya (heart), and mahāsukha (crown of the head), which correspond to four of the seven chakras in the Shaiva Mantramarga universe, namely Svadhisthana, Anahata, Visuddha, and Sahasrara. However, depending on the meditational tradition, these vary between three and six. The chakras are considered psycho-spiritual constituents, each bearing meaningful correspondences to cosmic processes and their postulated Buddha counterpart.
