If there are futures lives, heavens or hells ... I will fetch water and chop wood, seeking to live in a gentle way, avoiding harm to self and others (not two, by the way).
If there are no future lives, heavens or hells ... I will fetch water and chop wood, seeking to live in a gentle way, avoiding harm to self and others (not two, by the way).
I do not know if, in the next life, that "gentle way, avoiding harm" will buy me a ticket to heaven and keep me out of hell or allow a better rebirth ... but I know for a fact that it will go far to do so in this life, today, where I see people create all manner of "heavens and hells" for themselves and those around them by their harmful words, thoughts and acts in this life.
And if there is a "heaven and hell" in the next life, or other effects of Karma now ... well, my actions now have effects then too, and might be the ticket to heaven or good rebirth.
In other words, whatever the case ... today, now ... live in a gentle way, avoiding harm to self and others (not two, by the way) ... seeking to avoid harm now and in the future too.
