Non-violence is the greatest Dharma; So too is all righteous violence.

Some of the logic behind 'nature worship' practised by our ancestors was actually a way of keeping the balance and conserving nature's essential features from total extinction and elimination.
One such example is of the 'Sarpakkaavu' or sacred groves where the snake god is worshipped in Kerala. It was a very effective prevalent nature conservation measures till a few decades ago. . Such sacred groves used to be kept untouched and the devotees used to light lamps and keep food preparations and leave them for the snakes as offerings. Our ancestors knew that forest cover was needed to balance water conservation, temperature maintenance, and this helped birds and other creatures to take shelter there. They knew that even snakes were needed to keep the nature's balance. The urbanisation causing almost extinction of snakes from urban areas has only helped the rats and bandicoots to grow to damaging potential and menace.
These were given some religious connection only to make people comply with sincerity and total faith.
