HYMN XXXVII

A charm to secure long life and dominion to a prince

1To me hath come this word given by Agni, fame, force and
   might, and strength, and life, and lustre.
  May Agni too bestow on me three-times a hundred manly
   powers.
2For mighty strength, for action, I receive thee, for manly power,
   to last a hundred autumns. p. 242
3For conquering strength and energy and vigour
  I fasten thee for chieftainship, for bearing royal dominion
   through a hundred autumns.
4With Seasons and with Season-groups, for vigour and extended
   life.
  With splendour of the perfect year we fasten thee about the
   neck.
