Introduction

While the Buddha was staying at Savatthi, a band of monks, having received subjects of meditation from the master, proceeded to a forest to spend the rainy season (vassana). The tree deities inhabiting this forest were worried by their arrival, as they had to descend from tree abodes and dwell on the ground. They hoped, however, the monks would leave soon; but finding that the monks would stay the vassana period of three months, harassed them in diverse ways, during the night with the intention of scaring them away. Living under such conditions being impossible, the monks went to the Master and informed him of their difficulties. Thereon the Buddha instructed them in the Metta sutta and advised their return equipped with this sutta for their protection.

The monks went back to the forest, and practicing the instruction conveyed, permeated the whole atmosphere with their radiant thoughts of metta or loving-kindness. The deities so affected by this power of love, henceforth allowed them to meditate in peace. The discourse gets divided into two parts. The first detailing the standard of moral conduct required by one who wishes to attain Purity and Peace, and the second the method of practice of metta.

This is to be done by one skilled in aims who wants to break through to the state of peace: Be capable, upright, & straightforward, easy to instruct, gentle, & not conceited, content & easy to support, with few duties, living lightly, with peaceful faculties, masterful, modest, & no greed for supporters.

Do not do the slightest thing that the wise would later censure.

Think: Happy, at rest, may all beings be happy at heart. Whatever beings there may be, weak or strong, without exception, long, large, middling, short, subtle, blatant, seen & unseen, near & far, born & seeking birth: May all beings be happy at heart.

Let no one deceive another or despise anyone anywhere, or through anger or irritation wish for another to suffer.

As a mother would risk her life to protect her child, her only child, even so should one cultivate a limitless heart with regard to all beings. With good will for the entire cosmos, cultivate a limitless heart: Above, below, & all around, unobstructed, without enmity or hate. Whether standing, walking, sitting, or lying down, as long as one is alert, one should be resolved on this mindfulness. This is called a sublime abiding here & now.

Not taken with views, but virtuous & consummate in vision, having subdued desire for sensual pleasures, one never again will lie in the womb.

-- Sn 1.8 (PTS: Sn 143-152)

“He or she who wants to attain peace should practice being upright, humble, and capable of using loving speech. He or she will know how to live simply and happily, with senses calmed, without being covetous and carried away by the emotions of the majority. Let him or her not do anything that will be disapproved of by the wise ones.

“(And this is what he or she contemplates):

“May everyone be happy and safe, and may their hearts be filled with joy.

“May all living beings live in security and in peace—beings who are frail or strong, tall or short, big or small, visible or not visible, near or faraway, already born, or yet to be born. May all of them dwell in perfect tranquility.

“Let no one do harm to anyone. Let no one put the life of anyone in danger. Let no one, out of anger or ill will, wish anyone any harm.

“Just as a mother loves and protects her only child at the risk of her own life, we should cultivate boundless love to offer to all living beings in the entire cosmos. We should let our boundless love pervade the whole universe, above, below, and across. Our love will know no obstacles. Our heart will be absolutely free from hatred and enmity. Whether standing or walking, sitting or lying, as long as we are awake, we should maintain this mindfulness of love in our own heart. This is the noblest way of living.

“Free from wrong views, greed, and sensual desires, living in beauty and realizing Perfect Understanding, those who practice boundless love will certainly transcend birth and death.”
