Here are two short, traditional Jain Sanskrit/Prakrit lines about jiva (the soul), along with simple meanings.

1) Jīváśca

• Original: जीवाश्च
• Transliteration: jīvāśca
• Meaning (arth): The souls (jīva) are also substances (dravya). This sutra states that jiva is one of the six fundamental substances in Jain philosophy. It is part of the basic taxonomy used to explain the nature of the world. Digambara and Śvetāmbara traditions both accept jīva as a proper dravya with its own sentient nature. ( wisdomlib.org)

2) Parasparopagraho jīvānām

• Original: परस्परोपग्रहो जीवानाम्
• Transliteration: parasparopagraho jīvānām
• Meaning (arth): The function of the souls is mutual help or interdependence—jīvas help one another. This describes how beings support each other in the social and ethical sense (teacher-student, master-servant, etc.), and it is a principle often cited in Jain ethics. It appears as verse 5.21 in the Tattvartha Sutra, a key text respected by both major Jain traditions. ( wisdomlib.org)

Note on tradition

• These lines come from the Tattvartha Sutra, which is respected across Digambar and Śvetāmbara communities. When discussing sutras and their meanings, Digambara and Śvetāmbara may have slightly different commentaries, but the core terms and the essence about jiva as a conscious soul and its ethical duties remain aligned.

If you’d like, I can share a brief, authentic paraphrase of how these verses are explained in traditional Jain commentaries.
