Dakshinachara
Dakṣiṇācāra is a tantric term meaning 'right-hand path'. It is used to describe tantric sects that do not engage in heterodox practices. In contrast, vamachara is used to describe particular tantric practices that are considered heterodox.
Etymology
N. N. Bhattacharyya explains the Sanskrit technical term [Ācāra|] as follows:
The means of spiritual attainment which varies from person to person according to competence.... Ācāras are generally of seven kinds – Veda, Vaiṣṇava, Śaiva, Dakṣiṇa, Vāma, Siddhāṇta, and Kaula, falling into two broad categories – Dakṣiṇa and Vāma. Interpretations vary regarding the nature and grouping of the ācāras.
[Dakshina|] means 'right'. For this reason, the term dakṣiṇāra is often translated "right-hand path".
