It cannot be the
original Damdami Bir, maybe a copy at best.
There is a mistake in the first line of the first pauri of Jap (Jee Sahib), come on!
ਸੋਚੈ ਸੋਚਿ ਨ ਹੋਵਈ ਜੇ ਸੋਚੀ ਲਖ ਵਾਰ॥
is written as
ਸੋਚੈ ਸੋਚਿ
ਨਿ ਹੋਵਈ ਜੇ ਸੋਚੀ ਲਖ ਵਾਰ ॥
Interesting Point:In Birs/Pothis/Gutkas these days,
੧ is only written after ਹੈ ਭੀ ਸਚੁ ਨਾਨਕ ਹੋਸੀ ਭੀ ਸਚੁ as
ਹੈ ਭੀ ਸਚੁ ਨਾਨਕ ਹੋਸੀ ਭੀ ਸਚੁ ॥੧॥
Many people from different groups use this to nonsensically 'prove' that Mool Mantar is up to ਨਾਨਕ ਹੋਸੀ ਭੀ ਸਚੁ because that is the first place where
੧ shows up, so that must mean that this is where Mool Mantar is complete.
We all know this is not the case.
ਆਦਿਸਚੁਜੁਗਾਦਿਸਚੁ॥ ਹੈਭੀਸਚੁਨਾਨਕਹੋਸੀਭੀਸਚੁ॥੧॥
^ That is a Salok!
What proves it even more are the pair of double lines around Jap which indicate that Jap is the title of the Bani:
॥ ਜਪੁ ॥
How do we know the title of the Bani if 'Jap' is part of Mool Mantar?
Jap is clearly a title.
Also ਆਦਿਸਚੁਜੁਗਾਦਿਸਚੁ॥ ਹੈਭੀਸਚੁਨਾਨਕਹੋਸੀਭੀਸਚੁ॥੧॥ never comes up again in Guru Granth Sahib Jee as part of Mool Mantar/Manglacharan, so I don't know why people egotistically insist that it's part of Mool Mantar.
So what is the interesting point here?
Look at the picture of the 'Damdami Bir', and look after Prasad or GurPrasad.
You see it as follows:
ੴਸਤਿਨਾਮੁਕਰਤਾਪੁਰਖੁਨਿਰਭਉਨਿਰਵੈਰੁਅਕਾਲਮੂਰਤਿਅਜੂਨੀਸੈਭੰਗੁਰਪ੍ਰਸਾਦਿ॥ ੧ ॥ ਜਪੁ ॥ ॥ਆਦਿਸਚੁ॥ਜੁਗਾਦਿਸਚੁ॥ਹੈਭੀਸਚੁ॥ਨਾਨਕਹੋਸੀਭੀਸਚੁ॥੧॥
Have you ever seen any other handwritten Saroops like this?
Because here there is a clear indication of Mool Mantar completing at Prasad/GurPrasad.
It is interesting because maybe there are other Saroops like this too, but they have been removed by anti-Sikh elements.
The same way Saroops without Raagmala have been removed/destroyed.
The same way some groups are printing Gutkas/Birs without ॥ on both sides of ਜਪੁ, so they make it look like this:
ਜਪੁ ॥
which is completely wrong. The reason they do this is to make it look like Mool Mantar goes to ਨਾਨਕਹੋਸੀਭੀਸਚੁ.
