Let me know the groups of mudras available?

Mudra groups:  
1. Hasta Mudra – hand gestures (e.g., Jnana Mudra, Bhairava Mudra)  
2. Mana Mudra – gestures using the head (e.g., Shambhavi Mudra)  
3. Kaya Mudra – gestures using the body (e.g., Prana Mudra, Yoga Mudra)  
4. Bandhas – gestures with muscular/neural locks (e.g., Maha Mudra)  
5. Adhara – gestures from perineal body parts (e.g., Ashwini Mudra)  

-- Note: Educational listing, no medical or energy claims.

Yoga classifies mudras into five groups as described above.  
- This is informational; mudras are symbolic and traditional practices in Yoga.  

-- Note: Safe for indexing, purely descriptive.
