Answer

Yes, in Digambar Jainism, saying “my mother will always be in my heart” is more in harmony with Jain values than saying “my mother is mine.”

Explanation

In Jain Dharma, the idea of possession and ownership is seen as a form of attachment. So the phrase “my mother is mine” can reflect possessiveness.

On the other hand, “my mother will always be in my heart” expresses:

• love
• respect
• gratitude
• remembrance

This is softer and less possessive.

But even this should be understood with Jain awareness:

• your mother is a separate soul
• you are a separate soul
• love should be pure, without bondage or clinging

Spiritual Understanding

Jainism teaches aparigraha and anattachment from possessiveness. So the ideal feeling is:

• “I respect my mother deeply.”
• “I am grateful to her.”
• “She remains lovingly remembered in my heart.”
• “But I do not claim her as my property.”

This keeps affection pure and spiritual.

Takeaway

In Jain thought, love with respect is good; possessiveness is not. So your second expression is better, because it shows love without ownership.
