yes nameless he did so, but i think he is doing the same with all faiths, just picking a branch. in all cases i think one month is not enough to grasp everything, but sure it's a good chance to built good bases for future.
Actually i'm following him, and from time to time i ask him questions, or add comments, and i've found his way of explaining is better than the real followers of the same faith, i would say more objective
what comes to his Sikh month, i still can't understand how he accepted the tradition/custom of wearing objects, i guess this is the most difficult part for me, i really have hard time understanding it (not only in Sikhism, but in all religions).
