This development of conjugal love for Krsna is not manifested in women only. The material body has nothing to do with spiritual loving affairs. A woman may develop an attitude for becoming a friend of Krsna, and, similarly, a man may develop the feature of becoming a gopi in Vrndavana. How a devotee in the form of a man can desire to become a gopi is stated in the Padma Purana as follows: In days gone by there were many sages in Dandakaranya. Dandakaranya is the name of the forest where Lord Ramacandra lived after being banished by His father for fourteen years. At that time there were many advanced sages who were captivated by the beauty of Lord Ramacandra and who desired to become women in order to embrace the Lord. Later on, these sages appeared in Gokula Vrndavana when Krsna advented Himself there, and they were born as gopis, or girl friends of Krsna. In this way they attained the perfection of spiritual life.
The story of the sages of Dandakaranya can be explained as follows. When Lord Ramacandra was residing in Dandakaranya, the sages who were engaged in devotional service there became attracted by His beauty and immediately thought of the gopis at Vrndavana, who enjoyed conjugal loving affection with Krsna. In this instance it is clear that the sages of Dandakaranya desired conjugal love in the manner of the gopis, although they were well aware of the Supreme Lord as both Krsna and Lord Ramacandra. They knew that although Ramacandra was an ideal king and could not accept more than one wife, Lord Krsna, being the full-fledged Personality of Godhead, could fulfill the desires of all of them in Vrndavana. These sages also concluded that the form of Lord Krsna is more attractive than that of Lord Ramacandra, and so they prayed to become gopis in their future lives to be associated with Krsna.
Lord Ramacandra remained silent, and His silence shows that He accepted the prayers of the sages. Thus they were blessed by Lord Ramacandra to have association with Lord Krsna in their future lives. As a result of this benediction, they all took birth as women in the wombs of gopis at Gokula, and as they had desired in their previous lives, they enjoyed the company of Lord Krsna, who was present at that time in Gokula Vrndavana.
