Yes. This is the “Manaha Jināṇam Sajjhāy” (often people remember only the starting words “Manaha Jināṇam …”). Below is the full sutra in English transliteration as preserved in Jain tradition:

Manaha Jināṇam Sajjhāy Sutra (Roman/English letters)

1. Mannaha jināṇamāṇaṁ, micchaṁ pariharaha,

dharaha sammattam chavvihi-āvassayammi, ujjutto hoi pai-divasaṁ.

1. Pavvesu posaha-vayaṁ, dāṇaṁ sīlaṁ tavo a bhāvo a,

sajjhāya namukkāro, parovayāro a jayāṇa a.

1. Jiṇa-puā jiṇa-thuṇaṇaṁ, guru-thua sāhammiyāṇa vacchallaṁ,

vavaharassa ya suddhi, raha-jattā tittha-jattā ya.

bhāsā-samīī chhajīva-karuṇā ya, dhammia-jaṇa-saṁsaggo, karaṇa-damo caraṇa-pariṇāmo.

putthaya-lihaṇaṁ pabhāvaṇā titthe, saḍḍhāṇa kiccameyaṁ, niccaṁ sugurū-vaesenaṁ.
