Answer

Generally, no — devas do not universally have jāti-smaraṇa as an ordinary faculty. Some devas may remember previous births due to special karmic causes or higher knowledge, but it is not considered a common or guaranteed trait for all devas.

Explanation

In Jainism, jāti-smaraṇa means remembrance of past birth or past births. This can arise in certain beings because of specific karmic conditions.

Devas are celestial beings, and they are often described as having higher knowledge than ordinary humans, such as avadhi jñāna in many cases. But that is not the same as saying every deva has past-life remembrance.

So the balanced Jain understanding is:

• Jāti-smaraṇa is possible in some beings
• It is not automatic for all devas
• Some devas may know their previous birth, but not all necessarily do

Spiritual Understanding

Jain Dharma teaches that knowledge depends on karma and its unfolding. Even a high heavenly birth does not mean complete liberation from karmic limitations. True and complete knowledge comes only with the destruction of ज्ञानावरणीय karma, and full perfection is found in kevala jñāna.

Takeaway

So, in short: some devas may have past-life remembrance, but devas in general are not said to have jāti-smaraṇa by default.
