The Logassa Sutra (also spelled Logassa Sutra or Loggaas Sutra) is a revered Jain prayer found in the Jain Agamas, specifically in the Śvetāmbara tradition. It is a part of the daily prayers (Pratikraman) and is dedicated to the veneration of the twenty-four Tirthankaras of Jainism.

Here is the traditional text of the Logassa Sutra (in Prakrit):

Logassa Ujjugareṇaṃ, Panchasāvva Sāhūṇaṃ, Chattārīṃsaṃ Puvvayāraṃ, Arihantāṇaṃ Uvāsaeṃ, Esiṃ Dhammo Suyambudho, Chattārīṃsaṃ Purāṇaṃ, Naṃdissaṃti Namokkāraṃ, Jina Varaṃ Namāmihaṃ.

A more detailed version (with the names of Tirthankaras):

Logassa ujjoyagareṇaṃ panchasāvva-sāhuṇam, Chattārīṃsaṃ purāṇaṃ, arihantāṇam uvāsayam.

Namo arihantāṇam (I bow to the Arihants), Namo siddhāṇam (I bow to the Siddhas), Namo āyariyāṇam (I bow to the Acharyas), Namo uvajjhāyāṇam (I bow to the Upadhyayas), Namo loe savva-sāhūṇam (I bow to all the Sadhus in the world).

Eso pancha-namokkāro (These five obeisances), Savva-pāva-ppaṇāsaṇo (Destroy all sins). Mangalaṇam cha savvesim (Amongst all auspicious things), Padhamam havai mangalam (This is the foremost auspicious one).

The Logassa Sutra is recited to express deep reverence and devotion to all 24 Tirthankaras and to seek spiritual upliftment.
