Answer

If you are standing in front of a Manastambh in a Jain temple, the most common mantra to recite is the Navkar Mantra.

Explanation

A Manastambh is a pillar of humility. It reminds us to become free from ego and bow down internally.

You can stand quietly with folded hands and recite:

णमो अरिहंताणं
णमो सिद्धाणं
णमो आयरियाणं
णमो उवज्झायाणं
णमो लोए सव्वसाहूणं

This mantra is traditionally recited with reverence and a pure heart.

Spiritual Understanding

Standing before a Manastambh means remembering:

• humility
• respect
• self-discipline
• surrender of ego

In Jain Dharma, true devotion is not only in words, but in inner feelings of simplicity and reverence.

Takeaway

The best mantra to say is the Navkar Mantra. If you do not know the full mantra, even silent bowing with श्रद्धा and a pure mind is meaningful.
