Answer

In Jain Dharma, devas are generally said to have avadhi jñāna by birth, so they can often know past lives directly. But jāti-smaraṇa is not usually described as a universal or automatic feature of every deva.

Explanation

• Jāti-smaraṇa means remembrance of previous birth or births.
• Devas are born with a higher form of knowledge called avadhi jñāna.
• Because of this, many devas may know their past existence without needing the ordinary kind of recollection that humans sometimes experience.
• So, if you ask strictly, devas may know past lives, but jāti-smaraṇa is not usually emphasized as their standard natural faculty.

Spiritual Understanding

This shows an important Jain teaching: higher birth does not mean liberation. Even devas, despite their subtle knowledge and heavenly pleasures, still remain within samsara until the bondage of karma is destroyed.

Takeaway

Short answer: Devas can know past lives, but jāti-smaraṇa is not generally described as their main or universal feature in Jain tradition.
