So pathetic was the torture of Guru Tegh Bahadur that his body had to be cremated clandestinely (a follower burned down his own home to cremate the Guru's body) at Delhi while his severed head was secretly taken four hundred kilometers away to Anandpur Sahib for cremation.

He himself became their disciple (Wonderful is Guru Gobind Singh, himself the Master and himself the disciple). The Five Beloved Ones were astonished at such a proposal, and represented their own unworthiness, and the greatness of the Guru, whom they deemed God's representative upon earth. He gave the Sikhs the name Singh (lion) or Kaur (princess).
