Look at it this way - if we theoretically say yes one can take birth again as a Sikh, how will that affect their Simran now? Also if one takes birth again how will they remember that they are supposed to do Simran? What will stop them from asking this question again?

Bro, I don't know if I naam jap or not. .. honestly. How do I know if the name that I said with my tongue is being accepted in the dargah when my mind is wavering and is not steady. So I am scared.
Another thing I was thinking.
The population of the Humans in the world is 7.8 Billion.
Where as the population of all animals - mammals, reptiles, insects, bacteria, virus and all ocean life and other creatures far exceeds than the 7.8 billion number
On top of that add all the other rooms in pret, hellish forms.
Getting a Human Life seems winning a lottery and on top of that human birth in a good family, plus human birth in a Sikh family seems near impossible?
I want to know what happens to a person who is born a Sikh and dies and did not do Naam Jap? are they given Sikh birth again or have they lost?
