Why is it advised to not carry Gangajal from Kashi (Varanasi) | The Times of India

Another reason that is given as to why people should not take Gangajal from Kashi is that people come to Kashi, dead or alive, to attain Moksha. And so, when the deceased are burned on the pyre and their ashes are cremated or dissolved in the Ganga, it is a part of the soul that is being offered to river Ganga. And so, if by chance you happen to take Gangajal from Kashi, and in that water are parts, ashes, or remains of a deceased soul, you are going to be an obstacle in their journey to moksha. Collecting and taking this water away from Kashi will disrupt the cycle of death and rebirth, the soul might not completely attain moksha, and will pose a problem for you later.
