Answer

In the 6 Āvashyak, the one connected with “hospital” is usually understood as:

Pratikraman

Explanation

The 6 Āvashyak are daily essential Jain practices. Pratikraman is like a spiritual hospital because:

• In a hospital, the body’s illness is treated.
• In Pratikraman, the soul’s faults, mistakes, and sins are examined and purified.
• We ask forgiveness for wrong thoughts, words, and actions.
• We take a vow to avoid repeating those mistakes.

So, just as a hospital helps cure physical disease, Pratikraman helps cure inner spiritual disease like anger, ego, deceit, greed, and carelessness.

Takeaway

Pratikraman is called the spiritual “hospital” among the 6 Āvashyak because it helps heal and purify the soul.
