Answer

Sohliya Tap generally refers to a Jain tapasya connected with the number 16, because “Sohliya” means sixteen.

In Jain practice, it is commonly understood as a form of austerity where the devotee performs fasting or disciplined food-related restraint according to a prescribed pattern involving 16 observances.

Explanation

The exact method of Sohliya Tap can vary depending on the Jain tradition, gaccha, family custom, or guidance of one’s Guru. Therefore, it should be performed only after understanding the proper rules from a learned Jain sadhu, sadhvi, or knowledgeable shravak/shravika.

In general, such tapasya may include:

• Fasting or restricted eating
• Increased samayik, pratikraman, japa, and swadhyay
• Control over taste and bodily comfort
• Devotional worship and inner purification

Spiritual Understanding

The purpose of any Jain tap is not merely to avoid food. Its deeper purpose is:

• To reduce attachment to the body
• To develop self-control
• To shed karma through restraint and awareness
• To strengthen devotion toward Arihant, Siddha, Guru, and Dharma

Takeaway

Sohliya Tap is a Jain austerity associated with sixteen observances. Since its exact rules may differ by tradition, it is best to learn and perform it under proper Jain religious guidance.
