A Krishna Conscious marriage is not based on sense gratification but rather mutual cooperation between husband and wife for making advancement in spiritual life and also for raising Krishna Conscious children. It is said in the Vedas that one should not take on the responsibility of Parenthood unless he can deliver the child from the repeated cycle of birth, death, disease, and old age. So in this way mold your life in service to the Lord and be happy. -- "Srila Prabhupada"
