All three are Jain traditions: Digambar, Shwetambar, and Sthanakvasi. It is not appropriate to say only one is “real Jain” and the others are not.

In Jain Dharma:

• Digambar follows one traditional path of practice and interpretation.
• Shwetambar follows another traditional path.
• Sthanakvasi is a reform movement within the Shwetambar tradition that emphasizes simpler worship and meditation.

So, all are Jain, but they differ in practices, scriptures accepted, and monastic traditions. The true essence of Jain Dharma is Ahimsa, Satya, Asteya, Brahmacharya, and Aparigraha.

If you want, I can also explain the main differences between Digambar, Shwetambar, and Sthanakvasi in a simple table.
