The four calculations

A word on the practice

Kartsi — the "white calculation" — was systematised in Tibet in the eleventh and twelfth centuries by masters like Drogön Chögyal Phagpa, drawing on the Kālacakra Tantra from India, the sixty-year cycle inherited from China, and the indigenous Tibetan calendar tradition. It is one of the five great sciences a Tibetan scholar was trained in — alongside grammar, logic, medicine, and craft.

A full Kartsi chart calculates the animal year and element of your birth from the sixty-year cycle, the phase of your srog (life-force) and lus (body) across the twelve years around your birth animal, and your wang thang and klung rta — the personal power and windhorse that rise and fall with each new Losar (Tibetan New Year).

What it is good for

Timing. When your windhorse is high, take the bold journey. When your srog is low, do the retreat instead of the mountain climb. Traditional Tibetan households consult a kartsi almanac (lo tho) at Losar and again at each birthday, quietly adjusting the year's plans.

What it is not

Not fate. Not a script. The great Kagyu master Jamgön Kongtrül was clear: astrology describes the wind, but you still sail the boat. If a low year appears, that is when the practice deepens — not when you give up.
