Diksha in Jainism is the formal act of renunciation to become a monk or nun. It is a significant spiritual step taken by a householder or already renounced practitioner, and it is described in Jain scriptures with various particularities for different Tirthankaras.

If you are asking about a specific Tirthankara (for example, who his or her mother and father were, or any story about “dev lok” involvement at the time of renunciation), please share the exact name. The details can vary between Digambara and Śvetāmbara traditions, and there are distinct legends for different Tirthankaras.
