Sat Sri Akaal
What is the purpose of Kirpan da Amrit for babies?
Ishna ji,
Guru Fateh.
Sikhi is a very interesting concept which gives the person the tools to evolve with time.
Baptism in other religions is done some days after birth. It is a big thing in the Catholic side of Christianity. However, the Protestant took its thunder away with a new concept called 'Born Again Christian' where one is baptised at any age. Bluntly speaking, it is a ploy of guilt concocted by the Protestants.
In Hinduism, the ritual is 'Mundan' where they shave off the baby's head no matter the gender.
Khandei de Pahul is an optional thing for a Sikh as it was the last thing created by our 10th Guru when Sikhi had already been thriving for a couple of centuries. This is a very responsible commitment for the one who is ready and 'getting ready' for this affair is very subjective.
But we all know a baby has no idea about it. Hence Kirpan da Amrit becomes merely a dogmatic ritual which has nothing to do with Sikhi per se.
