As far as I know,Hinduism does not condemn tattoos,not even religious/spiritual tattoos.

I really like tattoos and so I decided to get tattooed things as symbols of my fidelity to the gaudiya-vaishnava Divine Couple(Radha and Krishna).

Ultimately, in my opinion, for a Hindu to have religious/spiritual tattoos is and must remain an individual and personal choice.

These are all my tattoos:
