Kaja is not a standard or widely used term in Paushad (Paushadh) as described in Jain scriptures and practice. Paushad refers to a vow where a householder lives like a monk for a set period to stop new karmas and burn old karmas. Typical aspects include taking a sankalp, staying in a clean space, limiting speech, practicing celibacy, and following a simple diet and monastic-like routine. There are variants in Digambar and Śvētāmbara traditions, but “kaja” does not form a recognized part of the Paushad framework in canonical or traditional guidance. If you meant a different word (for example, a specific practice or term within Paushadh like upavās, pratikraman, or samayik), please share that detail and I’ll explain it precisely.
