Great sharing here - of Kalyug and meeting of Guru Nanak dev jee-- here is more: Baba Nand Singh jee confirming::
This is a Sakhi taken from Anand Chamatkaar Sant Baba Nand Singh Ji told the Sangat how Kaljug met him
Sri Hazur Baba Nand Singh was meditating in Deo Seaal (now in Pakistan). The place selected was a thick jungle. Babaji liked meditating in jungles and avoided cities. Babajis nitnem was to rise and mid night, do ishnan and then simran. Mahapurakh used to say the advent of Sri Satguru Nanak Dev took place at 12.21 am.
One night Baba ji was meditating as usual. Suddenly a person appeared before him. Only his eyes were glowing the rest was all black. Hazur said who is it?. No one spoke. After saying this twice times no one spoke and baba ji waved his stick and said who is it? speak now. And Kaljug said "I am Kaljug the king of this age". Baba ji said what do you want, why have you here after me in this jungle. Kaljug said you meditate day and night come under my rule i will give you everything you want.
Baba ji said there is only one rule at the moment, that is the rule of Guru Nanak. But you go on. Kaljug said why do you meditate this much? you get frozen in the cold water. I will give you a palace to stay in and all the riches you want. Baba ji said i have made a vow never to touch a note in my life and now you may leave before you are forced out of here. Kaljug said i would have told you right now how powerful i am at doing things, but because of your "Sukhmani" i can not doing anything. Babaji well done you have told your own cure.
Before Baba Nand Singh ji would listen to 5 Sukhmani Sahib paath every day. However, after this meeting Babaji said to Kaljug i will start Sukhmani forever at Nanaksar. Kaljug tried his best to stop this 24 hour Paath even hurling the Paathis around and scaring them he eventually gave up and left.
Sukhmani Sukh Amrit Prabh Naam Bhagat Jana Ke Mann Bisraam.

This sakhi is also in the Janam sakhi of Guru Nanak Dev Jee. Baba Nand Singh Ji shared this with the Sangat so i doubt it is made up. Kaljug also came again in the form of a cat. This Sakhi is in Isher Chamatkaar (life story of Baba Isher Singh Ji)
Baba Isher Singh Ji was helping in the construction of the new Nanaksar Thaath near Jagroan, Ludhiana. At mid night baba ji went to do bisraam and told the sewadar to stand guard, since the prakaash of Dhan Sri Guru Granth Sahib ji was in the other room. Suddenly a black cat came. The sewadar fell asleep and didn't notice the cat. The cat went into the room. Baba ji at once went into the room and the cat had left but tore up the rumala and ghuldasta. baba isher singh ji said to the sewadar " i told you to keep guard and you fell asleep". Babaji at once did ardas and begged for forgiveness. Baba Nand Singh ji appeared and said "that cat was Kaljug. Where you have started this immense sewa of building the Thaath, you should also start the Sewa of Naam".
Baba Isher Singh ji started Sampat Akhand Paaths of Guru Granth Sahib ji at Sri Nanaksar. 24/7 Paaths of Sukhmani and japji.
