In Jainism, Lord Mallinatha is the 19th Tirthankara of the current Avasarpini (descending half-cycle of time). Jains offer reverence to all Tirthankaras, including Lord Mallinatha, through various prayers and devotional hymns known as stutis, stavans, and vandanas.

A common prayer recited for all Tirthankaras, including Mallinatha, is the Namokar Mantra (Navkar Mantra), which is the most fundamental and universal Jain prayer:

णमो अरिहंताणं। णमो सिद्धाणं। णमो आयरियाणं। णमो उवज्झायाणं। णमो लोए सव्वसाहूणं।

(Namo Arihantanam Namo Siddhanam Namo Ayariyanam Namo Uvajjhayanam Namo Loe Savva-sahunam)

This mantra pays homage to the five supreme beings in Jainism, including the Tirthankaras.

Additionally, there are specific hymns and stavans dedicated to Lord Mallinatha. An example of such a prayer is:

श्री मल्लिनाथ जिनेन्द्राय नमः। Shri Mallinath Jinendraya Namah.

Or, more elaborately, some Jain texts and temples may use the following salutation:

मल्लिनाथ प्रभु की जय। Mallinath Prabhu Ki Jai.

Devotees may also recite the Mallinath Stavan or chant verses that praise the qualities, life, and teachings of Lord Mallinatha. The specific text and language of these prayers can vary by Jain sect (Shwetambar or Digambar) and regional tradition.

If you are looking for a more specific stavan or stuti, many Jain prayer books contain hymns such as "Mallinath Bhagwan ni Aarti," "Mallinath Bhagwan na Stavan," and so forth, which are sung in temples and at home.
