Though heavenly beings have attained a peaceful state of mind and body, as long as there is a human being who is suffering, if they are concerned to save him from his suffering and if they practice positively to help the buddhas for the sake of the salvation of all living beings, they rise to the world of the buddhas (bukkai), the highest realm of living beings. This is because even heavenly beings make strenuous efforts for the sake of serving others, making them happy, and saving them from their sufferings. In such merciful actions and creative lives they feel a deep joy, and this is the way that leads them to the enlightenment of the buddhas.

As illustrated by the diagram of the ten realms of living beings (jikkai) … , the way to enter the world of the buddhas starts in the world of human beings (ningen-kai). It is concerning this point that Nichiren said, “A hundred years’ practice in the Pure Land is not equal to the merit of a day’s practice in the impure land.” Unless heavenly beings continually come down to the world of human beings and practice to save all living beings from their sufferings, they cannot become buddhas. For this reason, all the Brahma heavenly kings descended from the peaceful heavens, desiring to receive the Buddha’s teachings so much that they gave up their palaces, that is, their peaceful lives.
