Panchamakara
Panchamakara, also known as the Five Ms, is a Tantric term referring to the five substances used in a Tantric practice.
Taboo-breaking elements are only practiced literally by "left-hand path" tantrics ( vāmācārins), whereas "right-hand path" tantrics ( dakṣiṇācārins) oppose these.(Rawson, 1978).
