Aayambil is a Jain vrata (fast/auspicious vow) traditionally observed by lay Jain followers. In this practice, the devotee undertakes a day-long or specified-period fast and takes a very limited, single meal or a highly simplified meal. The focus is on penance, purification of mind and body, and reducing karmic causes through restraint, prayer, and self-discipline.

Key points:

• Purpose: spiritual purification and gradual reduction of karmic burden through restraint and devotion.
• How it’s done: typically involves a vow to eat a minimal, prescribed set of foods in one sitting, often with additional prayers or rituals. The exact rules can vary by community and temple.
• Differences: there are small variations between Digambar and Shwetambar practices in terms of permitted foods, number of meals, and the days on which Aayambil is performed.
