Answer

In the six Āvashyak, the one that is considered the “compounder” is generally understood as Pratikraman.

Explanation

The six Āvashyak are:

• Sāmāyik
• Chaturvimshati Stava
• Vandanā
• Pratikraman
• Kāyotsarga
• Pratyākhyān

Pratikraman is called the “compounder” because it includes or brings together repentance, reflection, confession of faults, asking forgiveness, and renewal of right conduct.

Spiritual Understanding

Through Pratikraman, a Jain reflects on mistakes done knowingly or unknowingly and purifies the soul by seeking forgiveness and resolving not to repeat those faults.

Takeaway

Among the six Āvashyak, Pratikraman is the main practice that works like a “compounder” by combining purification, repentance, and spiritual correction.
