Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
With full, undiverted attention, Aditi thought of the Supreme Personality of Godhead and in this way brought under full control her mind and senses, which resembled forceful horses. She concentrated her mind upon the Supreme Lord, Vasudeva. Thus she performed the ritualistic ceremony known as payo-vrata.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
This is the process of bhakti-yoga.
 
anyabhilasita-sunyam
 jñana-karmady-anavrtam
anukulyena krsnanu-
 silanam bhaktir uttama
 
“One should render transcendental loving service to the Supreme Lord Krsna favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service.” One simply has to concentrate upon the lotus feet of Vasudeva, Krsna (sa vai manah krsna-padaravindayoh). Then the mind and senses will be controlled, and one can engage himself fully in the devotional service of the Lord. The devotee does not need to practice the hatha-yoga system to control the mind and senses; his mind and senses are automatically controlled because of unalloyed devotional service to the Lord.
