English: Detail of Mata Jito appending sugar crystals to Amrit from a fresco that was located in the original Akal Takht building.
Guru Gobind Singh baptising the “Five Beloved Ones’.
"The 10th mural illustrated the most significant event in the history of the Sikhs, the first baptising ceremony in which Panj Pyare (the five beloved), name given to the five Sikhs, Bhai Daya Singh, Bhai Dharam Singh, Bhai Himmat Singh, Bhai Muhkam Singh and Bhai Sahib Singh, who were so designated by Guru Gobind at the historic divan at Anandpur Sahib on March 30, 1699 receive at his hands Khande di pahul i.e. rites of the two-edged sword. An inscription in the mural in Gurmukhi characters read: "Panja Singhan nu amrit chhakaya Sahib Dasveen Padshahi Guru Gobind Singh ji ne." The Panj Pyare stood with folded hands before the Guru and Guru’s wife Mata Jitoji brought patashas (sugar crystals), which were put in an iron bowl and stirred with two-edged sword by the Guru to make Amrit, the nectar of immortality."

An old depiction of Mata Jito from the pre-1984 Akal Takht (destroyed in Operation Blue Star 1984). Guru Gobind Singh is to her right preparing Amrit whilst Mata Jito is bringing the Patashe to append to it with the original/inaugural group of Panj Pyare behind her. Mata Jito is wearing a chunni (Indic headscarf for women).
"Image is of a mid-19th century fresco (probably painted under patronage of Ranjit Singh) depicting the events of Vaisakhi 1699. Mata Sundri [incorrect, actually depicts Mata Jito] puts sugar crystals into the pahul while Guru Gobind Singh stirs." (description by @yungbhujang)
Caption reads: “Panja Singha nu Amrit chakkaya” “Sahib Dasvi Patshahi Guru Gobind Singh Ji Ne”
