I am going to use Sikhism as an example of how human religion is built on using methods to be acceptable to their Creator.
There are innumerable examples of the things that humans think they need to do in order to be acceptable, both in religion and in society.
Sikhism, like most all religions, is a group of beliefs, usually compiled into dogma by a highly regarded teacher/prophet, that say “If I do this, The Almighty will accept me, and if I don’t I will not be acceptable.”
It is not laughable, it comes from deep inside the human mind that has a need for acceptance. Our modern society is rife with this, in identity confusion, etc.
Most mental illness rises from whether a person is accepted or rejected by those he feels he needs to be accepted by.
In the case of Sikhism, hair represents a pact with God, as it did in the Nazerite tradition in Judaism.
One other similarity between Sikhism and most other religions is that The Almighty (or whatever name they choose to call the Almighty) even though he is seen as the Creator of all, has conditions on his acceptance of what he created.
I am going to state this clearly: I do not believe that our connection with the Almighty has any conditions on it. Our belief is based on human interactions.
When humans get hold of these things, like everything else, they create a club where those that they agree with get to be members, and those who they do not agree with are enemies.
This is not the way that is true and consistent with Reality.
