Why are we just guessing, do we really know? Certainly not as per Guru Ji
ਅੰਤੁ ਨ ਜਾਪੈ ਕਿਆ ਮਨਿ ਮੰਤੁ ॥
What is Lord's motive? It's limit is not known.
ਉਸ ਅਕਾਲ ਪੁਰਖ ਦੇ ਮਨ ਵਿਚ ਕਿਹੜੀ ਸਲਾਹ ਹੈ-ਇਸ ਗੱਲ ਦਾ ਭੀ ਅੰਤ ਨਹੀਂ ਪਾਇਆ ਜਾ ਸਕਦਾ
AS per Guru ji, who created, He knows, Watch His creation and just say wismaad( amazing !) This is the way I feel, if others are able to guess right, congratulations.
