During Paryushan, Jains greet each other and share messages that encourage spiritual upliftment, forgiveness, and self-reflection. Here is a suitable message to mark the start of Paryushan:

"Paryushan Parva is a time for self-purification, reflection, and seeking forgiveness. May this auspicious period inspire us to practice non-violence (ahimsa), truth (satya), and forgiveness (kshama) in our daily lives. Let us strive to overcome our inner weaknesses and progress on the path of liberation. Michhami Dukkadam."
