Answer

No, in commonly accepted Jain tradition, Ravan is not considered to be a Tirthankar in the next Chovisi.

Explanation

In Jain Dharma, the next Chovisi will have 24 new Tirthankaras, but Ravan is not listed among them in the traditional Jain understanding.

Ravan is known in Jain texts as a powerful and highly intelligent person, but also as someone with great attachment, pride, and karmic bondage. Because of this, he is not regarded as a future Tirthankar in mainstream Jain belief.

Spiritual Understanding

Jain Dharma teaches that Tirthankarhood is attained through:

• supreme purity of conduct
• complete detachment
• deep equanimity
• destruction of intense karmas

So greatness in power or intelligence alone does not make one a Tirthankar. Only the highest spiritual purity does.

Takeaway

According to Jain tradition, Ravan is not going to be a Tirthankar in the next Chovisi. Tirthankarhood is reserved for souls with the highest level of spiritual liberation and detachment.
