HYMN XXV

A prayer to fever, as a charm against his attacks

1When Agni blazed when he had pierced the Waters, whereat the
  Law-observers paid him homage,
  There, men assever, was thy loftiest birthplace: O Fever, yield-
   ing to our prayer avoid us.
2If thou be fiery glow, or inflammation, or if thy birthplace call
   for chips of fuel,
  Rack is thy name, God of the sickly yellow! O Fever, yielding
   to our prayer avoid us.
3Be thou distress, or agonizing torment, be thou the son King
  Varuna hath begotten,
  Rack isthy name, God of the sickly yellow! O Fever, yielding to
   our prayer avoid us.
4I offer homage to the chilly Fever, to his fierce burning glow I
   offer homage. p. a24
  Be adoration paid to Fever coming each other day, the third, of
   two days running.
