Answer

In the Jain text I found, the practice of dharma / tirthankar-pravachana prabhavana is linked with Bhagwan Vasupujya, Bhagwan Arishtanemi, and Bhagwan Parshvanath. It is presented as one of the causes for binding Tirthankar-nam-and-gotra-karma, not as a single exclusive person for all cases. ( jainqq.org)

Explanation

The text says that the twenty auspicious practices can lead to the bondage of Tirthankar-nam-karma, and one of those practices is jinashasan / tirthankar pravacana prabhavana. In the appendix, the names shown next to that point are Vasupujya, Arishtanemi, and Parshva. ( jainqq.org)

Spiritual Understanding

In Jain Dharma, prabhavana means uplifting and glorifying Dharma through right conduct, devotion, and inspiring others toward the path of liberation. Because it benefits many souls, it becomes a very powerful meritorious cause. ( jainqq.org)

Takeaway

So, if you are asking for the names mentioned in this context, the answer is: Vasupujya, Arishtanemi, and Parshvanath. ( jainqq.org)
