Namkha for a person/project, event
A Namkha can be made for a person, a project or an event.
E.g. Lings and Gars of the Dzogchen community has Namkhas made for dates of their registration.
When I needed to sell a part of an apartment to leave Russia, I made Namkhas specifically for this occasion. It was a hopeless option on market, but with Namkhas I managed to sell the small part of property I owned.
1 person/project/event can have 4 Namkhas in total
1) made for Tibetan hour of birth
2) made for Tibetan day of birth
3) made for Tibetan month of birth
4) made for Tibetan year of birth
The most accurate Namkha is one for the Tibetan hour of birth.
If you don’t know your accurate time of birth, it’s recommended to have one for day of birth.
