There is no doubt that in his subsequent birth his past behavior makes the person suffer much more due to this burden of acquired sanskaras. But, with the intensity of his suffering, the redeeming factor is the speed with which these acquired sanskaras get wiped off. They are wiped off in proportion to the intensity of suffering. Along with the wiping off of the acquired sanskaras, his own sanskaras also get wiped off speedily.
Just as an unauthorized person, posing as a saint, proves a source of benefit to thousands, so also he proves of harm to many. All this is a play in illusion!
As an opium addict feels happy to give a tiny bit of opium to another, and that other, when he gets the taste of it, hands over another small dose to a friend, they thus create a circle of opium-eaters. The two or three persons close to the "opiumized" saint of our discourse start spreading news that such-and-such a woman was blessed with a child, and that another got her wish fulfilled, and that he, a "saint," performed many such miracles. A clique of followers is created around the opiumized saint.
This happy picture does not last long, for after some years it so happens that at least one person finds out one day that his Master is a fraud and is not God-realized. The impact of such a great setback in his confirmed belief is so forceful that all his sanskaras, which he had inadvertently transferred on to the "saint" in his belief and devotion, all of a sudden recoil on him spontaneously and overburden him afresh. Thus, the person who had placed faith in the opiumized saint suffers a great deal.
Let us view the picture from another angle: Suppose I am the opiumized saint and you love me and revere me as the Perfect Master. Your love becomes so deep and your faith so great that you actually make progress on the spiritual path, and really begin to have experiences of the Path. In this instance, you are surely benefited at the hands of an opiumized saint. Whereas in the previous case, the opiumized saint has done a great harm. Through such false saints harm and benefit recoil and accrue.
