Aho, Kayam (or Aho-kayam) is a small Jain expression found in old Prakrit passages.

• Aho = an exclamatory interjection like "Oh!" or "alas," used to express emphasis or reverence in prayers and mantras.
• Kayam (kaya) = body, and in many Jain phrases it is connected with vows, discipline, or the body as the field of karma. In context with phrases like aho-kayam, it appears in devotional or confessional formulas where the speaker addresses or salutes the body and its restraint.

Note: Exact nuances can differ slightly between Digambar and Śvetambar traditions, but the core sense is an exclamatory address (aho) plus reference to the body or karmic discipline (kayam/kaya-samphasam) in ritual language. If you want, I can point to a specific Jain text where aho-kayam appears and explain that verse in more detail.
