salavrkanam strinam ca
sakhyany ahur anityani
nutnam nutnam vicinvatam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O demons, as monkeys, jackals and dogs are unsteady in their sexual relationships and want newer and newer friends every day, women who live independently seek new friends daily. Friendship with such a woman is never permanent. This is the opinion of learned scholars.
