The three most important things to be eliminated before attaining God-realization are greed, lust and ninda; the last, meaning "back-biting," is the worst and most disastrous.

One can overcome greed, or even lust, though both of these are very hard to get over; but the worst and most difficult of all to eliminate is the habit of ninda: speaking ill and trying to find faults or flaws in others; because this particular act or vice incurs the burden of sins or what is technically termed as sanskaras of others.
