The Navkar Mantra itself does not contain 216 adjectives. It is a mantra of five salutations to the supreme worthy beings:

1. Arihant
2. Siddha
3. Acharya
4. Upadhyay
5. Sadhu

If by “216 adjectives” you mean the 216 divine qualities associated with the revered Jain beings in some traditional explanations, then this is a later explanatory count, not the mantra’s original wording. Different Jain traditions may explain these qualities in slightly different ways.

Very brief understanding

• Navkar Mantra = homage mantra
• It does not directly list 216 adjectives
• Its essence is reverence, purity, and liberation-oriented remembrance

If you want, I can also give:

• the Navkar Mantra original text
• its meaning in simple Hindi/English
• or the qualities of Arihant, Siddha, Acharya, Upadhyay, and Sadhu in Jain tradition.
