Rain falls according to its own nature; the land yields its crop according to its own destiny. Whatever seed is sown, that fruit will come at the end; profit and loss belong to each alone. A lamp has no partiality within it; honest person and thief receive its light alike. Crows feed on scraps, partridges on gravel, but the royal swan feeds on pearls. Says Tuka, here, love is the only cause; as one's love is, so Narayana ripens for each.
