Rehit is the guarantee of the technology of the Guru. Guru Ji guarantees the resulting life of beauty upon the living of the rehit. The basic rehit is practiced by all Sikhs. Only foolish people think their way is somehow better. The rehit is for personal growth not to measure who is a Sikh. Accepting the full rehit of Guru Gobind Singh is humility. It's the capacity of our limited understanding to see that there was a perfect incarnation, there was a supreme master far wiser and greater than us. Guru Gobind Singh gave us his sweet blessing, he gave us a discipline to acheive greatness, he gave us the immortal nectar of God and infused his spirit in it. He gave the example of Khalsa (purity) by which the world shall be ruled and is in need of for survival. Rehit is the beauty of the individual Sikh who accepts the greatness of the Guru's blessing and commits to a life of purity with undying service to humanity. When the wandering mind 'deluded by doubt' leaves duality and accepts the full hukam of Guru Ji, that person can begin on a long rewarding journey to meet with the creator.
