A mudra is a symbolic or ritual gesture or pose in Hinduism, Jainism, and Buddhism. The term "mudra" translates from Sanskrit as "gesture," "mark," or "seal". Mudras are believed to have a powerful effect on prana, the vital life force energy, and are therefore typically performed alongside pranayama or meditation to amplify the effects of these practices. There are around 400 known mudras across various religious and spiritual traditions. While some mudras involve the entire body, most are performed with the hands and fingers. Mudras are used in the iconography of Hindu and Buddhist art of the Indian subcontinent and described in the scriptures, such as Nātyaśāstra, which lists 24 asaṁyuta ("separated", meaning "one-hand") and 13 saṁyuta ("joined", meaning "two-hand") mudras.

Mudras are categorized as hand hasta mudras, body (kaya) mudras, and consciousness (citta) mudras. Hand mudras are the most common in yoga, and they tend to accompany postures such as padmasana (Lotus Pose), vajrasana (Thunderbolt Pose), or sukhasana (Easy Pose). Each individual mudra has unique symbolism and is thought to have a specific effect on the body and mind by clearing energetic pathways. Mudras are believed to stimulate the flow of prana throughout the body, quieten the mind by focusing it on the simple touch of our hands or fingers, and intensify the power of our practice.

Here are three common mudras:

1. Jnana Mudra: This mudra is performed by touching the tip of the index finger to the tip of the thumb, with the other three fingers extended. It is known as the mudra of wisdom or knowledge and is believed to improve concentration and memory.

2. Anjali Mudra: This mudra is performed by bringing the palms together in front of the heart, with the fingers pointing upwards. It is also known as the mudra of salutation and is used as a gesture of respect and gratitude.

3. Varun Mudra: This mudra is performed by touching the tip of the little finger to the tip of the thumb, with the other three fingers extended. It is believed to increase the water content in the body and restore balance to the Sacral Chakra.

Performing mudras is said to establish a distinct relationship and have a distinct influence on the body, mind, and prana. Mudras are higher rituals that help the pranas, chakras, and Kundalini to awaken, restore pranic balance within the koshas, and allow subtle energy to be directed to the upper chakras, resulting in a higher state of consciousness.
