Hindi
हे अर्जुन ! रजोगुण और तमोगुण को दबा कर सत्वगुण, तत्वगुण और तमोगुण को दबा कर रजोगुण, वैसे ही सत्वगुण और रजोगुण को दबा कर तमोगुण होता है अर्थात् बढ़ता है |
English
At times O Arjuna, the first element of nature, SATTVA, rules over the other two GUNAS (powers of nature) known as RAJAS and TAMAS. However, at times the RAJAS part of human nature takes over and rules the SATTVA and TAMAS elements and similarly the TAMAS mode of nature may overpower the SATTVA and RAJAS modes of nature.
