Shaheed Bhai Harjinder Singh Jinda & Shaheed Bhai Sukhdev Singh Sukha were not Amritdhari from day one. When they cut their Kes to carry out the Seva they actually cried because they felt really bad for doing so.
When they were in Jail, they grew their Kes and begged for Amrit. However, they never received Amrit, but were told by Baba Thakur Singh Ji "no government or power in this world can prevent you from receiving the gift of Amrit. Baba Ji then said that, the king of kings, the saint of saints, that beautiful king of this world and the next Satguru Sri Guru Gobind Singh Ji Maharaj would give these two Singhs Amrit personally hereafter."
Some people are very anti Kharkhoo Singh because they think the Singhs were too much into siphai part but not the sant part of Sikhi. These two amazing souls had a nitnem of 16-18 hours long. It is said that they were reading 11 Sukhmani Sahib, 25 Japji Sahib and 7 Bania (Japji Sahib, Jaap Sahib, Tav Prasaad Savaiya Sahib, Chaupee Sahib, Anand Sahib, Rehraas Sahib and Kirtan Sohila Sahib) daily!!!
