Jaga Chintamani Gatha is the Jag Chintamani Sutra / Chaityavandan. It is recited in Jain temple worship and during Pratikraman, and it praises the Tirthankars as the refuge and guide of the world. ( jainuniversity.org)

Opening lines: > Ichchhā-kāreṇa sandisaha bhagavan! > Chaityavandana karu? Ichchham. > Jaga-cintāmaṇi! Jaga-nāha! Jaga-guru! > Jaga-rakkhaṇa! Jaga-bandhava! > Jaga-satthavāha! Jaga-bhāva-viakkhaṇa! > Atthāvaya-santhavia-ruva! > Kammattha-vināsana! Chauvisampi jinavara! > Jayantu a-ppadihaya sāsana. ( jainuniversity.org)

Simple meaning: “O Lord, please allow me to perform Chaityavandan. You are the jewel that removes the world’s suffering, the lord, teacher, protector, brother, guide, and knower of inner feelings. Your forms are established on Ashtapad, you destroy karmas, and may the 24 Tirthankars’ teachings forever remain victorious.” ( jainuniversity.org)
