Namaste everyone, I just found out your plight of loosing your stones to Hawaiian natives.  I am an artist, painting ceilings and artwork in Hindu Temples here in the States.  I found the story quite remarkable in the fact that knowing Hindus like I do, you have given up this sacred stone in a most gracious manner in the end, as I would not expect anything else from you.  I am American, but have been learning about Hindu ways and practices in my continued artistic ventures.  I am on a quest myself, to continue painting for Hindu temples around North America.  My latest project was a 1600 square foot ceiling mural for the New Hindu Temple of Southwest Florida, in Fort Myers, Florida.  My experience was such a wonderful one, that I now have a temple at home and when I travel, take several little things with me to help me keep my good Dharma spirit in tact.  I only wish for you that you continue to go to the site for you know Shiva is still there, waiting for your next step of future teachings.  You will find the way to another kind of spirit for the area you have protected for so long.  Feel wonderful for all the time you took to take care of this site.  All of you are grieving, but you must find a new way to bring Dharma back into a positive way, for if not, all the good feelings of this site will go away.  Keep your smiles still lighting the way for your children and families to have a place to practice your beliefs.  You can view my artwork by this link.
