PURPORT

Although due to feminine shyness there were many hindrances to embracing the dear husband Lord Sri Krsna, the queens performed that act by seeing Him, by putting Him in the core of their hearts, and by sending their sons to embrace Him. Still, the act remained unfinished, and tears rolled down their cheeks despite all endeavors to check them. One indirectly embraces the husband by sending the son to embrace him because the son is developed as part of the mother's body. The embrace of the son is not exactly the embrace of husband and wife from the sexual point of view, but the embrace is satisfaction from the affectionate point of view. The embrace of the eyes is more effective in the conjugal relation, and thus according to Srila Jiva Gosvami there is nothing wrong in such an exchange of feeling between husband and wife.
