You who seeking own happiness punish or kill beings who also long for happiness,will not find happiness after death.
You who seeking own happiness does not punish or kill beings who also long for happiness,will find happiness after death.
“If a man commits a sin,let him not do it again;let him not delight in sin:pain is the outcome of evil.”
“Even an evil-doer sees happiness as long as his evil deed has not ripened;but when his evil deed has ripened, then does the evil doer see evil.”
“Let no man think lightly of evil,saying in his heart,It will not come nigh unto me. Even by the falling of water-drops a water-pot is filled;the fool becomes full of evil,even if he gather it little by little.”
“If a man offend a harmless,pure,and innocent person,the evil falls back upon that fool,like light dust thrown up against the wind.”
“Some people are born again;evil-doers go to hell;righteous people go to heaven;those who are free from all worldly desires attain Nirvana.”
