I read you, however, I understand that by following the refuge vows, one ensures a human rebirth.
Correct?
And yet, the refuge vows make us refrain from non virtuous actions,
they are not vows that makes us engage in virtuous actions creating white karma...
We don't do evil, yet we don't do virtuous.
Thus it is grey karma that is created created, right?
Can you help me understand this point? ( from HR )
Simply taking refuge and following the vows will only protect us from lower realm rebirths for a few lifetimes. It is not a guarantee.
The real protection comes from practicing moral discipline understanding the laws of karma after taking refuge. Why? , Without deep conviction in karma , we will continue to break our vows even if we have them, we will not be able to generate correct motivations to fully potentialize whatever positive actions we are doing. Observing the laws of our country does not necessarily make one a moral person because it is not coming from one's own wisdom about the faults of negative behaviour but rather from the fear of punishment.
HR, your understanding of grey karma here is pretty sound ! Grey of neutral karma can also be actions like coughing , sneezing, breathing which have no consequences as they are involuntary actions. Actions which are very mild can also be placed under the grey karma category, whether they are positive or negative.They are too weak to produce any results - like diluted medicine.
