Kulekhara
So here is very nice description how we can materially become happy. These are all description of material happiness, svṛddhāḥ, very flourished cities and towns. So how it is flourished? Now, supakvauṣadhi-vīrudhaḥ. The herbs and plants and trees and creepers, they are all luxuriously grown and sufficiently supply the needs of the human being. Every plant and creeper is useful for human being. We do not know how to use them. Experienced men, they collect so many auṣadhi. Vanauṣadhi, latā loke jāyate paramaṁ hitam. We are neglecting these herbs and vegetables, but because we do not know how to use them, we have to meet so much bill of the doctors. But there are everything complete.
