In Jainism, it may be possible to meet your mother in a heavenly realm only if your karmas lead both souls there and into a similar life there. But heaven is not permanent in Jain Dharma, and family relationships do not remain forever in the same form.

Jainism teaches that:

• the soul takes rebirth according to karma,
• heavenly life is temporary,
• true liberation is moksha, where the soul is free from birth and death,
• in moksha, there is no worldly family bond as we know it.

So the simple answer is: yes, a meeting may be possible in heaven, but it is not guaranteed, and it is not the ultimate goal in Jainism. The highest aim is liberation of the soul.
