Here is the commonly followed set of mantras and prayers used during samayik (sāmayika). The exact words can vary a little between Digambar and Śvetāmbar traditions, but the core elements are the same.

• Namokāra (Navkar) Mantra

- It is recited at the start to bow to the Panch-Parameṣṭhi. - Ardhamāgadhi (original form): नमो अरिहंताणं नमो सिद्धाणं नमो आयरियाणं नमो उवज्झायाणं नमो लोए सव्व saहूँणं - Brief meaning: I bow to the Arihants, to the Siddhas, to the teachers (Acharas), to the Upadhyayas, and to all Sadhus; this salutation helps destroy sins and fosters auspiciousness.

• Khamāsamānā (confession/apology) Sutra

- A short sutra often recited in samayik to seek forgiveness and express humility. A common form starts with: Ichchhāmi Khamā - Samāno! … and then asks for pardon for past transgressions. - Purpose: to acknowledge faults committed by body, speech, or mind, and to refrain from such faults during samayik.

• Sūtrās to begin samayik (Sāmāyikā Sthāpanāji and related)

- After the Namokāra and Khamā sāmanā, practitioners often recite the initial sutras that establish the session, then proceed to: - Nominal prayers such as Logassa (Logassa Sūtra) or a short recitation praising the Tīrthankaras (stuti) and a brief vandanā to a chosen Tīrthankara.

• Logassa Sūtra (Chant of the 24 Tīrthankaras)

- Recited aloud at a point in samayik to honor all Tīrthankaras and to cultivate equanimity toward all beings.

• Pratikraman and related contemplations

- Iriyāvahiyam Pratikramana and related prayers are recited to reflect on deeds, confess misdeeds, and vow to avoid them in the future. - This may include brief recitations of specific sutras (Sūtrās No. 5–7 and nearby mantras) and a mental vow to follow samayik rules.

• Kāyotsarga and final salutations

- Kāyotsarga (withdrawal of attention from the body) may be practiced, followed by a final Namokāra/Namotthunam and a concluding prayer to mark the end of the session.

Notes on differences

• The core practice and mantras above are common to both Digambar and Śvetāmbara traditions, but exact texts and sequence can differ slightly between lineages or regional practices.
• Many communities also include a short Bhaktamar or other stotra as part of the samayik, and some recite additional sutras or Prabhu Vandana according to their guru’s guidance.
