Growing Plants to attain Nirvana

Planting and preservation of trees are made sacred in religious functions.
The Varah Purana says,
"One who plants one peepal, one neem, one bar, ten flowering plants or creepers, two pomegranates, two oranges and five mangos, does not go to hell."

In the Charak Sanhita, destruction of forests is taken as destruction of the state, and reforestation an act of rebuilding the state and advancing its welfare. Protection of animals, too is considered a sacred duty.
