We must be fully equipped, and the preaching work by pairs of husband and wife will be an unique example to the world. Formerly the Acaryas were generally all Sannyasis, but Lord Caitanya, in His instruction to Roy Ramananda, who was a confidential devotee of Lord Caitanya, but a householder and responsible government official, Governor of Madras, has given open instruction that it does not matter what is the social or ecclesiastical order, if one is fully in Krishna Consciousness, he can act as Acarya. So all you boys and girls who are now married, follow this instruction of Lord Caitanya, and show vivid example to the world how man and woman can be united, not for sense gratification but for the service of the Lord.
