In Jainism, "tis chaubisi" refers to the lineage of twenty-four (chaubisi) Tirthankaras (spiritual teachers) in each half-cycle of time (Avasarpini and Utsarpini). The word "tis" means "thirty," but in this context, it is often a mispronunciation or variation of "teesa," denoting "three times," but most commonly, "chaubisi" on its own signifies the 24 Tirthankaras.

The 24 Tirthankaras are revered as the enlightened beings who have attained perfect knowledge (Keval Jnana) and have shown the path of liberation (moksha) to others. Their life stories, teachings, and symbols are central to Jain philosophy and practice.

So, when referring to "chaubisi" or "tis chaubisi," it means the veneration or listing of all 24 Tirthankaras, which is a common practice in Jain prayers, art, and temple architecture, as a mark of respect and remembrance of their teachings.
