Sanatan Sikhi is the true Sikhi, but not as how most simple minded folk understand it to be.. For those of you who do not know what Sanatan is, look it up.
But for the lazy people who will not bother to research beyond their mobile phone contacts list or this primitive forum, heres a simplified version.
Sanatan means beyond time - timeless. it is Aadh Dharam. Aadh, being beyond time. Sikhi Dharam is beyond time. This makes it SANATAN.
Instead of being scared of things that you dont understand, why dont you try and find out what lies beneath, rather than failing to see under the veil of ignorance that has shrouded people's eyes.
