Bad Karma

The practice of killing children has existed in human society for a long time–since time immemorial–but in the days of yore it was very rarely performed. At the present moment, however, in this age of Kali, abortion–killing of the child within the womb–has become very common, and sometimes a child is even killed after birth. If a woman performs such an abominable act, she gradually loses all her bodily luster... Any woman who has ever performed such an infamously sinful act must atone for it, but no one now is doing that. Under the circumstances, the women responsible must suffer in this life and the next. Those who are sincere souls...should refrain from such child-killing and should atone for their sinful activities by taking to Krsna consciousness very seriously. If one chants the Hare Krsna maha-mantra without offenses, all of one’s sinful actions are surely atoned for immediately, but one should not commit such deeds again, for that is an offense.
