As we read in the suttas, one give freedom from fear, hostility and oppression to immeasurable beings by following the five precepts. I do not entirely see however, how you give that freedom to an 'immeasarable' amount beings. Could someone explain the logic behind this?
Thanks in advance and may you be well
I think it refers to the fact that if one's sila is perfect, then there is literally no measuring the benefit it bestows upon other beings. You would only be able to measure that freedom if you set limits upon it ("I'll not harm anyone in my family or community, but if someone from outside attacks me or mine, then I'll strike back...") In such cases, the benefit one bestows extends thus
far (i.e. to a measurable, specified point) but no further.
This is not to say, of course, that the benefit is actually bestowed upon all beings; merely that you have not limited or measured it out according to your views on who deserves it.
something similar is found in formulations for metta-bhavana.
Thus above, below, & all around, everywhere, in its entirety, keep pervading the all-encompassing cosmos with an awareness imbued with good will — abundant, expansive, immeasurable, without hostility, without ill will.
