Antar mauna means inner silence. It refers to a yogic meditation technique that involves transforming and controlling thought processes through self-awareness and mindfulness.
Observe the observer without being observed -Krishnamurti
Yoga is dualistic philosophy. The observer stands with its nature. Isolation of the mind. If I am not in Samadhi I am not purusha. Purusha has nothing to do with samadhi.
To start with this meditation focus on:
- Sensory perception.
- Spontaneous thoughts (just noticing, feeling them).
- Just be aware of whatever is happening.
- Create and depose theme (you have to choose one theme, one thought or one situation that you will focus continuously).
- Use the mind to go beyond the mind.
