These are subtle forces influencing our behavior as well as every aspect of our physical, mental, and emotional world. The effects of sattva-guna, the mode of goodness, are seen when an atmosphere of peace, serenity, and harmony prevails in our environment and ourselves. Rajo-guna, the mode of passion, is felt as insatiable desire for temporary things, striving for more and more of them, and perpetual dissatisfaction. Tamo-guna, the mode of ignorance, is indicated when there’s laziness, depression, intoxication, and insanity. The 14th chapter of the Bhagavad-gita contains elaborate descriptions of the modes, their symptoms, how they affect us, and ultimately how to become free from their influence through the practice of bhakti-yoga, or Krishna consciousness.
