The fourteenth chapter of the Bhagavad Gita is called “Guna-Traya-Vibhaga Yoga,” which means “Yoga of the Three Gunas.” In this chapter, Lord Krishna explains the three gunas or qualities of nature (sattva, rajas, and tamas) and their influence on human beings.
Lord Krishna begins by explaining that everything in the universe, including human beings, is made up of the three gunas. Sattva represents purity, goodness, and knowledge, rajas represents passion, activity, and desire, and tamas represents darkness, ignorance, and inertia.
Lord Krishna explains that these gunas are constantly interacting with each other and influencing our thoughts, actions, and behaviors. He states that those who are dominated by the sattva guna are peaceful, content, and wise, while those who are dominated by the rajas guna are full of desires and actions, and those who are dominated by the tamas guna are lazy, deluded, and ignorant.
Lord Krishna advises Arjuna to strive for a state of balance between these three gunas, rather than being dominated by any one of them. He explains that one can achieve this balance through spiritual practices such as meditation, self-reflection, and self-control.
Lord Krishna concludes the chapter by stating that those who are able to transcend the influence of the three gunas and see the eternal, unchanging essence of the universe will attain supreme knowledge and liberation from the cycle of birth and death.
