In Digambara Jainism, diksha (renunciation) is a mature, adult decision. A child cannot become a Digambara monk.

• Typically, only a person who has reached a certain level of maturity (often age 18–20 or older, depending on the monastery) takes diksha to become a Digambara monk.
• In Digambara tradition, women do not become Digambara monks. They may renounce as Jain nuns in other contexts (often within Śvetāmbara practices or in mixed traditions). This is a doctrinal difference between Digambara and Śvetāmbara traditions, and there are various rulings about women and renunciation across traditions.

If you’re exploring this for someone specific, it helps to know which community or monastery you’re asking about, since practices can vary by lineage.
