If your Jain darshaniya idols are in good condition, give them with respect to:

• a Jain derasar / temple
• a Jain upashraya
• a Jain trust or sangh
• a Jain family who will keep them respectfully for worship

Please do not give them to be used as decoration or in a disrespectful way.

If any idol is broken, damaged, or not fit for worship, do not throw it casually. Keep it respectfully wrapped and take guidance from a Jain muniji, sadhviji, or local temple trustee for proper handling according to your tradition.

If you want, I can also tell you the proper Jain way to donate old idols at home.
