Here’s the clear difference:

• Ayambil (ayambil vrata): A fasting-style vrata where a Jain practitioner eats a very limited, simple, and often single-type meal (usually once a day or on specific days) with mindfulness and purification. It is a discipline of diet and conduct, not a mantra.

• Navkarvali (Navkar mantra): The fivefold salutation mantra to the five supreme beings in Jainism (Arihant, Siddha, Acharya, Upadhyaya, Sadhv-like beings). It’s a devotional recitation, not a fasting ritual. It is recited for spiritual purification and reverence.

So, 1 ayambil is not equal to Navkarvali. They are two different practices: one is a vrata (discipline/fast) and the other is a mantra for worship.

Notes:

• Navkar mantra is used by both Digambar and Shvetambar communities, though there can be small variations in pronunciation or added lines in some traditions.
• If you were asking about a specific text or format of Navkarvali, tell me which tradition you follow (Digambar or Shvetambar) and I can outline the exact wording and meanings.
