Answer

In Digambara Jainism, there is no scriptural guarantee that you will meet your mother in heaven. Jain doctrine says that souls are reborn according to karma, and deva-birth is only one possible rebirth; heavenly life is still within saṃsāra, not a permanent family reunion. ( wisdomlib.org)

Explanation

A key source is Tattvārtha Sūtra 4.1, which states that celestial beings are of four classes. The Digambara commentary explains that deva-status arises from the rise of nāma-karma. Jain cosmology also says that the place of rebirth depends on karma, and a soul may be born in a heaven in one birth and elsewhere in another. ( wisdomlib.org)

So, if both you and your mother happened to be reborn in the same heavenly realm at the same time, a meeting is theoretically possible. But that is an inference from Jain rebirth doctrine, not an explicit promise made by the texts. Jain writings also treat family relationships as part of worldly attachment, which is something renunciants detach from. ( jainpedia.org)

Spiritual Understanding

In Jain Dharma, the main goal is not reunion in heaven but liberation from karma and rebirth. Even heavenly life is temporary; the soul continues moving through births until karma is removed. ( jainpedia.org)

Takeaway

The honest Jain answer is: possible in theory, but not guaranteed and not promised as a doctrine. In Jainism, karma decides rebirth, not wish or attachment. ( jainpedia.org)
