Kausagg (Prakrit: kāusagga, Sanskrit: Kayotsarga) is a special Jain meditation of “letting go of the body.”

Simple meaning

• Kaya = body, Utsarga = giving up / releasing.
• So Kayotsarga means: giving up attachment to the body and turning attention towards the pure soul (ātma).

How it is done (basic form)

• Usually done standing absolutely still (sometimes sitting/lying for long practices).
• Feet steady, body straight, arms relaxed slightly away from the body.
• Eyes gently downcast or closed, breathing natural.
• Mind focused on:

- the soul, or - Namokar Mantra, Logassa, or other Jain sutras.

Purpose in Jain dharma

• To practice detachment from the body.
• To stop new karma from binding.
• To shed old karma through peaceful, steady meditation.
• It is an important part of Samayik, Pratikraman and Chaitya‑vandan in both Śvetāmbara and Digambar traditions (wording and sutras around it may differ slightly, but the meaning is same).

Duration

• Can be for a few minutes or up to a traditional one muhūrta (~48 minutes), depending on capacity and the ritual.
