  There are, bhikkhus, these five gifts, great gifts, primal, of long
  standing, traditional, ancient, unadulterated and never before
  adulterated, which are not being adulterated and will not be
  adulterated, not repudiated by wise ascetics and brahmins. What five?
  
  6(4) “Here, a noble disciple, having abandoned the destruction of
  life, abstains from the destruction of life. By abstaining from the
  destruction of life, the noble disciple gives to an immeasurable
  number of beings freedom from fear, enmity, and affliction. He himself
  in turn enjoys immeasurable freedom from fear, enmity, and affliction.
  This is the first gift, a great gift, primal, of long standing,
  traditional, ancient, unadulterated and never before adulterated,
  which is not being adulterated and will not be adulterated, not
  repudiated by wise ascetics and brahmins. This is the fourth stream of
  merit … that leads to what is wished for, desired, and agreeable, to
  one’s welfare and happiness.
  
  7(5)–(8) “Again, a noble disciple, having abandoned the taking of what
  is not given, abstains from taking what is not given … abstains from
  sexual misconduct … abstains from false speech … abstains from liquor,
  wine, and intoxicants, the basis for heedlessness. By abstaining from
  liquor, wine, and intoxicants, the basis for heedlessness, the noble
  disciple gives to an immeasurable number of beings freedom from fear,
  enmity, and affliction. He himself in turn enjoys immeasurable freedom
  from fear, enmity, and affliction. This is the fifth gift, a great
  gift, primal, of long standing, traditional, ancient, unadulterated
  and never before adulterated, which is not being adulterated and will
  not be adulterated, not repudiated by wise ascetics and brahmins. This
  is the eighth stream of merit an.iv.247 … that leads to what is wished
  for, desired, and agreeable, to one’s welfare and happiness.
