Hymns of the Atharva Veda, by Ralph T.H. Griffith, [1895], at sacred-texts.com
1The man, to whose house, when the fires have been taken up
    from the hearth and the oblation to Agni placed therein, the
   Vrātya possessing this knowledge comes as a guest.
 2Should of his own accord rise to meet him and say, Vrātya, give
    me permission. I will sacrifice.
 3And if he gives permission he should sacrifice, if he does not
    permit him he should not sacrifice.
 4He who sacrifices when permitted by the Vrātya who possesses
    this knowledge.
 5Well knows the path that leads to the Fathers and the way that.
    leads to the Gods.
 6He does not act in opposition to the Gods. It becomes his
    sacrifice.
 7The abode of the man who sacrifices when permitted by the
   Vrātya who possesses this knowledge is long left remaining in
    this world.
 8But he who sacrifices without the permission of the Vrātya who-
     possesses this knowledge.
 9Knows not the path that leads to the Fathers nor the way that
    leads to the Gods.
 10He is at variance with the Gods. He hath offered no accepted.
    sacrifice. p. 158
 11The abode of the man who sacrifices without the permission of
    the Vrātya who possesses this knowledge is not left remaining
    in this world.
