He lets his mind pervade one quarter of the world with thoughts of love, and so the second, and so the third, and so the fourth. And thus the whole wide world, above, below, around, and everywhere, does he continue to pervade with the heart of love, far-reaching, exalted, beyond measure. Just as a mighty trumpeter makes himself heard--and that without difficulty--in all the four directions; even so of all things that have the shape of life there is not one that he passes by or leaves aside, but regards them all with mind set free, and deep-felt love. Verily this is the way to a state of union with Brahma.

(Buddha Sakyamuni)
