Some traditions also chant:

If you want, I can also give you:

• the proper Jain stavan/mantra form,
• the meaning in simple words,
• or the stotra for Padmavati Devi.

Spiritual Understanding

In Jain Dharma, such prayers are not for worldly attachment, but for:

• protection in the path of dharma,
• inner strength,
• removal of obstacles,
• and devotion toward the Tirthankar tradition.

The real spiritual value lies in shraddha, purity, and right intention while chanting.

Takeaway

If you are looking for the popular devotional chant, use:

“Om Hrim Dharanendra-Padmavati Devi Namah”

If you want, I can also write it in Gujarati or Sanskrit-style pronunciation.
