Acquiring a skill has, according to Indian tradition, four stages: adheeti, bOdha, aacharaNa and prachaaram.
- adheeti (అధీతి) involves studying the subject with due attention.
- bOdha (బోధ) involves distilling what is studied into the essential knowledge of the subject.
- aacharaNa (ఆచరణ) is putting the knowledge to practice.
- prachaaram (ప్రచారం) involves passing that practical knowledge to others.
