Yesterday was the Parkash Divas (birthday) of Guru Ram Das Ji which will be celebrated at the Gurdwara Sahib this coming weekend.
A little bit of history:
Guru Ji was born October 9, 1534 to parents Haridas Ji and Mata Daya Ji. He was named Bhai Jetha Ji. He came across some Sikhs traveling to Goindwal, and upon meeting Guru Amar Das Ji he decided to stay there to do sewa. He then married daughter of Guru Amar Jas Ji, Bibi Bhani. When Guru Amar Das Ji was selecting a successor, he asked both of his son-in-laws to make platforms. Upon inspection, Guru Ji asked that they both be torn down and rebuilt over and over. The older son-in-law refused, however Bhai Jetha Ji continued to keep rebuilding the platform seven times. He then became the successor of Guru Amar Das Ji in 1574 at age of 40, and was named Guru Ram Das Ji (servant of God). Guru Ji created Ramdaspur (present day Amritsar). Guru Ji wrote the laavan (read at Anand Karaj/marriage) and 688 of the shabads in the Sri Guru Granth Sahib Ji. Guru Ji also designed Harmandir Sahib.
