It states that water does not come upon his hands by the force of a person. But why?
Barry Epstein, Dallas, USA
If you are referring to the case of Arisa d'Dalai, the irrigation trough, the idea is that the force of the person must be directly onto the hands. In this case, the person spilled the water into the trough and the water flowed towards the field (on its own) where the person put his hands under the flow.
