am a firm believer that Creator and Creation are much sidelined whilst those that wished to spread the message, have become the message, which, in my view was the opposite of what was preached,
this I consider to be a beautiful picture, which is worthy of hanging up, and acts as a reminder as to what we should be doing, interacting with Creation, forgiving, advising, helping, loving, and respecting the basic tenants of Sikhism, no rituals, no idol worship, no magic mantras, no Kundalini posturing, just plain old truthful living.
Although, give it a few more years, and I am sure the pictures will change, 100 years from now, Guru Nanak will probably have a few more arms, and a companion who is a giant turtle, in fact I can see the picture in my minds eye now. Maybe a 100 years ago, they were chuckling that Guruji would probably be depicted holding the very items he preached against.
I know what I would rather have on my wall to remember Creator, I cannot see what the difference is between a picture of Elvis and the current depiction of the Gurus, neither represent the true image of the person concerned,
