Sadhu vandana means reverence or salutation to the sadhus (Jain monks and nuns). It is an act of showing respect for their renunciation, discipline, and spiritual guidance. Typically it is done with joining palms (pranām), a bow or prostration, and sometimes with a short prayer or chant.

• Sadhu = the holy ascetics in Jainism (monks and nuns)
• Vandana = homage, salutation, or reverence

Note: The basic idea is the same in both Digambar and Shwetambar traditions, though the exact prayers or forms of the homage may differ by tradition.
