The Navkar Mantra, also known as the Namokar Mantra or Namaskar Mantra, is the most fundamental and revered prayer in Jainism. It is not part of the canonical Jain Agamas (scriptures), but it is a standalone, ancient mantra found at the beginning of many Jain prayer books and rituals.

Regarding your question about "sutras," the Navkar Mantra itself is not part of any specific sutra in the Jain Agamas, but its verses are composed in sutra form (concise aphorisms) and recited as a mantra by all sects of Jainism (Shwetambar, Digambar, and others).

In summary:

• The Navkar Mantra is not a part of a specific Agamic sutra, but it is a foundational prayer and appears in many Jain ritual texts and compilations.
• It is recited before almost every Jain worship, meditation, or study session.
• The mantra pays obeisance to the Panch Parameshti (five supreme beings): Arihant, Siddha, Acharya, Upadhyaya, and Sādhu (all monks).

If you want the mantra itself, here it is:

``` णमो अरिहंताणं | णमो सिद्धाणं | णमो आयरियाणं | णमो उवज्जायाणं | णमो लोए सव्वसाहूणं ||

Eso pancha namokkaro, savva pavappanasano Mangalanam ca savvesim, padhamam havai mangalam || ```
