Hence, a previous comment I made - What religion out there is not a "failed religion?"
Corruption has seeped in everywhere. Religion is twisted and used for one's self-interest - to actually promote fear, hate, and division, rather than love and tolerance.
Yeh. But Sikhi practiced in its actual true form, ie Gurbani followed 100% without twisting and corrupting it, is Truth.
Many Sikhs love to bring their Egos and Manmade rules to the forefront, failing to realize that the only way to actually become a Gurus Sikh is to deliver your head to Him on a plate and eradicate the Ego.
