"Adidev alvesaru" is a phrase sometimes mentioned in the context of Chaityavandan, a ritual in Jainism that involves the veneration of the Tirthankaras and the practice of spiritual reflection and discipline.

Chaityavandan is a central daily ritual for many Jains, especially among the Shwetambar sect. It includes prayers, recitations, and various postures (mudras) performed in front of images or symbols of the Tirthankaras, the liberated souls who have shown the path to liberation (moksha).

"Adidev" generally refers to the first Tirthankara, Lord Rishabhanatha (Adinath), who is considered the original (adi) divine being (dev) in Jain tradition.

"Alvesaru" is a term in some regional languages (like Gujarati or Kannada) that means "to bow down" or "to pay respects."

So, "Adidev alvesaru" in the context of Chaityavandan means "I bow down to Adidev (Lord Rishabhanatha)." This is a gesture of reverence to the first Tirthankara as part of the Chaityavandan ritual, expressing devotion, humility, and the desire to follow the path shown by the Tirthankaras.
