Vāmācāra is a tantric term meaning "left-hand path" and is synonymous with the Sanskrit term vāmamārga. It is used to describe a particular mode of worship or sadhana that uses heterodox things to sublimate for spiritual growth.

Panchamakara or Panchatattva, also known as the Five Ms, is the Tantric term for the five substances used in a Tantric practice. These are madya (alcohol), māṃsa (meat), matsya (fish), mudrā (grain), and maithuna. Taboo-breaking elements are only practiced literally by "left-hand path" tantrics (vāmācārins), whereas "right-hand path" tantrics (dakṣiṇācārins) oppose these.
