Answer

If by “Nakar Mantra” you mean the Navkar/Namokar Mantra, the Bhagavati Sutra is understood to contain an early expanded form of that salutation. In a scholarly discussion of the Bhagavati Sutra, the opening invocation is described as bowing to the five supreme beings — Arihantas, Siddhas, Acharyas, Upadhyayas, and Sadhus — and also to the Brāhmi script and the scriptures. Some editions read “arihantānam,” while others read “arahantānam.” ( jainqq.org)

Explanation

So, strictly speaking, the passage in the Bhagavati Sutra is not just the standard five-fold Namokar Mantra in its shortest form. It is an extended mangalacharan or obeisance that includes the core pañca-namaskār idea and adds two more respectful salutations. ( jainqq.org)

Spiritual Understanding

This is important because it shows that the heart of Jain prayer is reverence toward the worthy and the awakened. The Bhagavati Sutra presentation emphasizes humility, devotion, and respect for both the spiritual teachers and the sacred Jain tradition itself. ( jainqq.org)

Takeaway

In simple terms: the Bhagavati Sutra contains a form of Namokar-related obeisance, but in an expanded form rather than only the familiar five-line mantra. ( jainqq.org)
