Samādhi Pāda · Sutra 13
तत्र स्थितौ यत्नोऽभ्यासः
tatra sthitau yatno 'bhyāsaḥ
Practice is the effort to become established in that state.
Abhyāsa is defined as the sustained effort to maintain a stable and quiet mind. It is not just any repeated activity, but specifically work directed toward nirodha (the cessation of fluctuations).
Practice implies:
- Clear intention
- Constant effort
- Direction toward mental stillness
