Why some people are physically big and have less sexual energy? Why some people who are frail and sickly but have vigorous sexual energy? Some have sexual relations as often as sparrows and some are infrequent, but some have intercourse like elephant. Amidst the diversity in this area, Ayurvedic medicine has divided people in to four categories.
- Strong seasonally
- Gained strength by practice
- Acquiring strength by other ways like using herbs or Ayurveda therapies
- Strong by nature (perform like a bull)
