Pusta Krishna: You said in the Srimad-Bhagavatam that if one wants to increase the material standard of living, then they should increase also sex life. And this is what they are doing in India today.
Prabhupada: Yes. Without sex life one cannot be materially enthusiastic. And if you stop sex life, then you become spiritually advanced. This is the secret. If you stop sex life, then you become spiritually advanced, and if you indulge in sex life, then you will be materially enthusiastic. That is the difference between Western and Eastern culture. The whole Eastern culture is based on how to stop sex life, and here in the Western countries, how to increase sex life. They are eating meat, eggs, drinking wine. These things will enthuse sex life. And as soon as you get very satisfactory sex life, you become enthused to work hard. Therefore, for the karmis, marriage is necessary, because without sex life they cannot work. And for jnanis, yogis, bhaktas, sex life is prohibited.
