For instance, one can build a house at will on vacant ground without difficulty, but in empty sky one cannot. It is the same with bodhisattvas. Because they want to bring living beings to maturity, they seek to have a buddhaland, which cannot be sought in empty sky. Ratnakara, you should know that the straightforward mind is a bodhisattva's purified buddhaland. When he attains buddhahood, guileless beings will enter that land.
Firm determination is a bodhisattva's purified land.
So, Ratnakara, a bodhisattva begins practice according to his straightforward mind. As soon as he practices, he gains firm determination. The moment he gains firm determination, he keeps his thoughts under control. As he keeps his thoughts under control, he is in like behavior. As he is in like behavior, he ripens occasions for beings to attain Awakening.
