Gopala Campu 3.18 : "She [Durga] had a dark complexion and eight arms, holding the cakra and other weapons. She rode on a lion in the sky and was praised profusely by the devatas. [..]"
SB 10.51.19 "Inexhaustible Time, stronger than the strong, is the Supreme Personality of Godhead Himself. Like a herdsman moving his animals along, He moves mortal creatures as His pastime."
TIME AND CONSCIOUSNESS
SB 10.51.19 "Inexhaustible Time, stronger than the strong, is the Supreme Personality of Godhead Himself. Like a herdsman moving his animals along, He moves mortal creatures as His pastime."
When the soul falls into vitiated consciousness and desires to exploit material nature refusing the Lord, Durga takes control by the bewildering Time. When by the mercy of the saintly devotees the soul finds the way to return to consciousness, to awake from the slumber of the bodily conception of life, by rendering service to the Lord, the same Durga releases her grip, freeing the soul from the influence of Time, and as Radha accepts the service in the palm of her hand to present to the Lord. Because eternal Time is the eternality of Krishna's loving pastimes, Radha is the mistress of His time, eternal time.
So, Durga devi and Radharani are the same person in a different mood, the former is the most distant from the Lord and the latter is the closest.
