In the Jain Agams and standard ritual texts, there is no fixed unit called “1 Lodha” for counting Navkar (Namokar) Mantra. Different local traditions use their own practical counts. Common devotional counts you will see are 9, 27, 108, or 1008 Navkars, but “Lodha/Lodhiya” as a set number is not defined in the scriptures.

If your local sangh uses “1 Lodha” as a custom unit, its value depends on that local tradition or guru-vachan, not on a universal Jain rule.
