Answer

“Gachchhādhipati” means the head or spiritual leader of a Jain gaccha — a monastic lineage or sectarian tradition.

If you are asking how to respectfully greet all Gachchhādhipatis, you may say:

“Sarva Gachchhādhipati Bhagwanto ne vandan / naman.”

Meaning:

“Respectful bowing and reverence to all Gachchhādhipati Bhagwants.”

Explanation

In Jain tradition:

• Gaccha refers to a Jain monastic lineage or tradition.
• Adhipati means head, chief, or leader.
• Gachchhādhipati therefore means the head of a gaccha.

The respectful words naman, vandan, or vandana are commonly used to express reverence.

Takeaway

A respectful form would be:

“Sarva Gachchhādhipati Bhagwanto ne bhāv-pūrvak vandan.”
