“Svabhāva (innate disposition) – Nature of a person.
For example tendency to put on weight, liver problem,
muscular pains for no reason, changes in temperature.
This is why Āyurveda divides humans into 3 types.
Approximately Pitta–Sattva, Kapha–Tamas, Vāta–Rajas Guṇa.
We not only look at the physical structure,
but also how food affects the individual.
Heavy in the morning, etc.
For example different children in the family affected by the same food differently.”
