"Javannt Kevi Sahu Sutra" is not a standard or commonly known sutra within the primary Jain scriptures or liturgical texts. It appears there may be a spelling or transliteration error, or perhaps it is a regional or community-specific prayer or verse.

In Jainism, some of the most important and widely recited sutras include:

• Navkar Mantra (Namokar Mantra): The fundamental prayer of Jainism.
• Logassa Sutra: A significant Prakrit verse recited to pay respect to the 24 Tirthankaras.
• Uvasaggaharam Stotra: A hymn dedicated to Parshvanath, the 23rd Tirthankara.
• Kalyan Mandir Stotra
• Mangalacharana Sutras: Invocations at the beginning of rituals.

If you provide the correct spelling or more context (language, tradition, or content), I can try to help you further regarding Jain sutras or prayers. If you are asking about a specific Jain prayer or text, please clarify, and I will do my best to provide information based strictly on Jainism.
