So, basically, what started out as a Tantric Bhakti practice later became a sense-enjoyment group. That's sad. Might I ask how Gaudiya Vaishnavism was ever degraded? IDK much about Gaudiya history from Lord Chaitanya's disappearance to now.
The Sankrit term is Panchamakara, but it is usually just called 'The Five Ms' in the west (b/c each thing starts w/ an 'M'). There's:
Madya (wine)
Mamsa (meat)
Matsya (fish)
Mudra (a type of alcohol made from parched grain)
Maithuna (sexual intercourse)
However, when reading things like this, one must remember that there are two Tantric paths in Hinduism: Vamachara and Dakshinachara. Vamachara Tantrics practice each of the Panchamakara (or Five Ms) literally, while Dakshinachara Tantrics follow them symbolically, or don't practice them at all, but just look for what the divine metaphor could be in each (e.g.- wine representing intoxication in God consciousness, intercourse representing the divine union of Shiva-Shakti or Vishnu-Lakshmi, etc...).
