sorry King. I dont know much abt Sikhism. I think Avinash, Sam or Rinki can give a satisfactory answer of this ques. But I know abt Buddhism n Jainism a bit. Regarding relatioship between buddhism n Hinduism u can refer Chicago Address by Swami Vevekananda where he said that Jainism n Buddhism r part of Hinduism n they developed Hinduism n took it to new heights
