Sri Guru Gobind Singh Ji's eldest Sahibzada, Baba Ajit Singh Ji took birth on 29th Maagh, 1743 Bikrami (1686 C.E.). Below we have translated a beautiful passage from Kavi Sant Ren Prem Singh Ji's Sri Gur Pur Parkash Granth, which goes into the details of Baba Ji's Janam Sanskaar and how Baba Ji was named. Kavi Sant Ren Prem Singh Ji was a family descendant of Sri Guru Angad Dev Ji, and wrote their Granth based on the historical manuscripts preserved in their family of their ancestor Baba Binod Singh Ji (descendant of Sri Guru Angad Dev Ji, Hazuri Sikh of Sri Guru Gobind Singh Ji and first Jathedar of Budha Dal):
ਚੌਪਈ।।ਸ੍ਰੀ ਅਕਾਲ ਗੁਰ ਦਯਾ ਸੁ ਕੀਨ । ਜਨਮ ਸਜਾਦੇ ਪ੍ਰਾਤਹਿ ਲੀਨ।
With the grace of Akaal Purakh, the Sahibzada (Baba Ajit Singh Ji) took birth at Amritvela.

Sri Guru Gobind Singh Ji got prepared masses of Karaah Parshad, after Ardaas this was distributed in all the Sangat.
ਰਾਮ ਕੁਇਰ ਕੋ ਅਸ ਫੁਰਮਾਯੋ । ਅੰਭ ਕਟੋਰੇ ਮਹਿੰ ਮੰਗਵਾਯੋ।।੪।।
Guru Gobind Singh instructed Bhai Raam Koer Ji (the descendant of Baba Budha Ji) to bring a Bata (iron bowl) full of freshwater.
ਸਿਰੀ ਸਾਹਿਬ ਕੀ ਨੋਕ ਧੁਲਾਈ । ਕਛ ਮਿਸਟਾਨ ਬੀਚ ਤਬ ਪਾਈ।
Placing some sugar crystals into the water, Guru Ji placed the tip of their Sri Sahib (Kirpan) in the Bata.
ਸ੍ਰੀ ਜਪੁ ਪੌੜੀ ਪੰਚ ਉਚਾਰੀ । ਗੁੜ੍ਹਤੀ ਦੀਨ ਸਜਾਦੇ ਭਾਰੀ।।੫।।
