Vardhman Tap (also known as Vardhaman Tapa or Vardhaman Vrat) is a significant austerity observed by Jain devotees, named after Lord Mahavira (Vardhaman), the 24th Tirthankara. This penance is performed to seek spiritual upliftment, purification of the soul, and to commemorate the intense austerities practiced by Lord Mahavira.

Ambil in the Jain context refers to a simple, soupy preparation of rice and water, sometimes with a little salt and turmeric, and is often consumed during fasts as it is considered very basic and sattvic (pure).

Vardhman Tap: Key Points

• Duration: The Vardhman Tap is usually performed for 13, 21, 27, 41, or even more consecutive days.
• Practice: The devotee observes alternate day fasting (upvas) and on non-fasting days, takes only one meal (ekasana) of simple food, often just ambil.
• Ambil Days: On fasting days, the devotee may consume only ambil or sometimes just boiled water, depending on their capacity and the rules they follow.
• Purpose: This tap aims at reducing attachment to taste and material comforts, aiding in self-purification and development of spiritual virtues like forbearance, self-control, and detachment.

Rituals and Observance

• On the days when food is allowed, only very simple food (often just ambil) is taken, typically without spices, ghee, or other rich ingredients.
• Many Jains undertake this tap during holy periods such as Paryushan or during special occasions in the Jain calendar.
• Devotees recite prayers, perform meditation, and focus on spiritual reflection during the tap.

Significance

• Vardhman Tap is considered highly meritorious and is believed to help in destroying karmas.
• It is a form of tapasya (austerity) that aids in progressing on the path of liberation (moksha).

Note: Performing Vardhman Tap or Ambil Tap requires physical and mental preparation. It is recommended to consult with knowledgeable Jain monks or a Jain community leader before undertaking this austerity.
