Answer

Chadti-Utarati Siddhi Tap is a Jain austerity in which a person performs fasting or limited eating in an increasing and then decreasing pattern.

The word:

• Chadti means increasing or ascending.
• Utarati means decreasing or descending.
• Siddhi Tap refers to a spiritually disciplined tapasya performed with devotion, restraint, and the aim of inner purification.

In general, this tap follows a pattern where the austerity gradually increases step by step and then gradually decreases step by step.

Explanation

The exact method of Chadti-Utarati Siddhi Tap may vary according to Jain tradition, gaccha, guru-parampara, and the guidance of one’s Guru or Upadhyay.

A common understanding is that the tapasya is performed in a sequence such as:

• Beginning with a smaller level of austerity
• Increasing the austerity gradually
• Reaching a peak level
• Then decreasing the austerity gradually

For example, in some tapasya patterns, the number of fasting days or ayambil-type observances may increase step by step and then decrease step by step. However, the exact counts, rules, food restrictions, and completion method should not be assumed without guidance from a knowledgeable Jain Guru.

During such tapasya, the devotee usually maintains:

• Faith in Arihant, Siddha, Sadhu, and Dharma
• Samayik, Pratikraman, or other spiritual practices as suitable
• Control over taste and desires
• Non-violence in thought, speech, and action
• Humility and absence of pride about the tap

Spiritual Understanding

The purpose of Chadti-Utarati Siddhi Tap is not merely physical fasting. Its deeper purpose is:

• Karma nirjara — shedding of karmas through austerity
• Indriya niyantran — control over the senses
• Raga-dvesha reduction — weakening attachment and aversion
• Atma shuddhi — purification of the soul
• Vairagya — strengthening detachment from worldly pleasures

In Jain Dharma, tap is meaningful only when performed with right faith, right knowledge, and right conduct. If fasting is done with ego, competition, anger, or desire for praise, its spiritual value becomes reduced.

Important Guidance

Because Chadti-Utarati Siddhi Tap can involve intense austerity, it should be undertaken only:

• With the permission and guidance of a Jain Guru or learned authority
• According to one’s health and capacity
• With proper understanding of the niyam and vidhi
• Without harming the body through carelessness

Takeaway

Chadti-Utarati Siddhi Tap is a disciplined Jain tapasya of gradual increase and decrease in austerity. Its real aim is not hardship, but purification of the soul, control of passions, and progress toward liberation. For the exact vidhi, one should follow the guidance of one’s Guru-parampara.
