Six Main Non-Buddhist Schools

The Six Main Non-Buddhist Schools — a popular grouping of non-Buddhist schools.

According to the Dungkar Great Tibetan Dictionary:

• Vaisheshika (Skt. Vaiśeṣika; Tib. བྱེ་བྲག་པ་, Wyl. bye brag pa)
• Nyaya (Skt. Nyāya; Tib. རིག་པ་ཅན་པ་, Wyl. rig pa can pa)
• Samkhya (Skt. Sāṃkhya; Tib. གྲངས་ཅན་པ་, Wyl. grangs can pa)
• Mimamsaka (Skt. Mīmāṃsaka; Tib. དཔྱོད་པ་བ་, Wyl. dpyod pa ba)
• Jain (Skt. Jaina) or Nigrantha ('the naked ones') (Skt.; Tib. གཅེར་བུ་པ་, Wyl. gcer bu pa)
• Charvaka (Skt. Cārvāka; Tib. རྒྱང་འཕེན་པ་, Wyl. rgyang 'phen pa) or Brihaspati (Skt. Bṛhaspati; Tib. ཕུར་བུ་པ་, Wyl. phur bu pa)

It is nearly the same as the five tarka schools, except that the Nyaya are added.
