In Digambar Jainism, yes, it is possible in principle to meet your mother again in heaven (devalok) after both of you die — but it is not guaranteed.

Why:

• In Jainism, rebirth is determined by karma, not by family feeling alone.
• After death, a soul may be reborn in a deva gati if it has earned enough punya karma.
• So if both you and your mother are reborn in the same heavenly realm, you may meet there.

But Jainism also teaches:

• Family relationships are temporary in this life.
• After death, the soul’s next birth depends on its own karmas.
• So a mother and daughter do not automatically remain together in the next life.

As a female layperson in Digambar Jainism:

• You can perform dharma, vrat, samayik, pratikraman, dan, and shil.
• Through पुण्य karmas, you may be born in a good gati, even devalok.
• But the goal of Jain dharma is moksha, not heaven.

So the simplest answer is:

Yes, you may meet your mother in heaven if both souls are reborn there, but Jainism does not promise that.

If you want, I can also explain this in simple Digambar Jain terms of gati, punya, and rebirth.
