While we are living and remaining in this world, if we only pay attention to darkness and hopelessness, we will not see anything but darkness. But if we turn our attention toward light and hopefulness, then even if we have only a little hope, we will eventually be able to find a way to reach the light.
For this reason, the world environment and all the beings in it are not all bad. The beings in the world are not unilaterally vicious, and the external world is not exclusively poisonous and polluted. If we make efforts with a courageous heart, we can transform the world into a pure realm. We can transform the beings in the world so that they become the beautiful and majestic deities present within their minds.
