Answer

In Digambar Jainism, there is no clear teaching that you are guaranteed to meet your mother in heaven as a mother-daughter reunion. Jain sources describe heaven as a temporary rebirth realm determined by karma, not as a place where worldly family ties are promised to continue forever. ( jainqq.org)

Explanation

A Jain source says the soul’s next birth is determined by karma, and that heavenly life is still transient. Another Jain source on Samayik says Jains avoid family names and worldly attachments, because spiritual practice is meant to rise above such identities. So the safest Jain conclusion is: heaven is not taught as a guaranteed family reunion place. ( jsmw.org)

Spiritual Understanding

From a Jain point of view, the main aim is not reunion in heaven, but reducing karma and moving toward moksha. So even if a soul is reborn in a heavenly realm by punya, Jain teaching does not specifically promise that earthly family relationships will continue there in the same way. This is an inference from the cited teachings. ( jsmw.org)

Takeaway

So the direct Jain answer is: not as a guaranteed matter of doctrine. You may be born in a heavenly realm by karma, but Jainism does not clearly teach that you will certainly meet your mother there as your mother. ( jsmw.org)
