SB 5.16.18
yad-upajosanad bhavanya anucarinam punya-jana-vadhunam avayava-sparsa-sugandha-vato dasa-yojanam samantad anuvasayati.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The pious wives of the Yaksas act as personal maidservants to assist Bhavani, the wife of Lord Siva. Because they drink the water of the river Arunoda, their bodies become fragrant, and as the air carries away that fragrance, it perfumes the entire atmosphere for eighty miles around.
