A civilisational loss
One of your more quoted statements is that the Bagmati is dirty because there is too much money flowing in it.
Bagmati is nature. She needs to be honoured and feared like nature. Feared like a teacher. She does not like money. Hindus believe when they die, they will be reclaimed by the five elements or panchatatva—jal (water), prithvi (land), vayu (wind), agni (fire) and aakash (space or void). I’m almost 90 and very sensitive to the need to protect nature. It will then care for us. If you start handling nature in a bad way, it will not honour you. If we concentrate our science on these five elements, we may be able to revive the Bagmati. Maybe it will take a long time. The easiest way to revive the Bagmati now is by not thinking big projects.
