Parkha (Tibetan སྤར་ཁ, spar kha) is the Tibetan version of the eight trigrams (Chinese Bagua, 八卦, bāguà), adapted from the Chinese I Ching system and integrated into Tibetan Yungtsi astrology (འབྱུང་རྩིས).

The 8 Parkha with Tibetan Names

• ☰ Khen (ཁོན) — Heaven, father
• ☷ Khön (ཁོན) — Earth, mother
• ☳ Zin (གཟིན) — Thunder
• ☴ Zön (གཟོན) — Wind
• ☵ Kham (ཁམས) — Water
• ☲ Li (ལི) — Fire
• ☶ Gin (གིན) — Mountain
• ☱ Da (ད) — Lake

Application

By year of birth. In Tibetan astrology, Parkha is determined by year of birth (with separate tables for men and women) and is used for:

• Compatibility analysis
• Choosing auspicious directions
• Ritual planning

A Three-Layered Model

Parkha + Mewa + elements. The Parkha system combines with Mewa (མེ་བ, the 9 magic numbers) and elemental analysis (Yungtsi), creating a three-layered model of the Tibetan natal chart. This yields a significantly finer diagnosis than Parkha alone.
