"Gunas" Tendencias de la Naturaleza - Nature tendencies

"Toda vida evoluciona a partir de la capacidad diferenciadora de las tres fuerzas o tendencias de la naturaleza: la pureza, luz o serenidad (sattva), la pasión o acción (rajas) y la ignorancia, oscuridad o inercia (tamas).
Todos tienen en ellos esas tres hebras (gunas, literalmente 'hebras') en distinta proporción y su conducta dependerá, como te he dicho, de la que predomine."

"How three modes of material nature bind the spirit soul to the body:
Sattv or goodness, Rajas or passion, activity; and Tamas or ignorance, inertia --- these three modes (Ropes, Gunas) of material Nature (Prakriti) fetter the eternal individual soul (Jeev) to the body, O Arjun. (14.05) Of these, the mode of goodness (Sattv) is illuminating and good, because it is pure. Sattv fetters the living entity (Jeev) by attachment to happiness and knowledge, O sinless Arjun. (14.06) Arjun, know that the mode of passion (Rajas) is characterized by intense craving and is the source of desire and attachment. Rajas binds the living entity (Jeev) by attachment to (the fruits of) work. (14.07) Know, O Arjun, that the mode of ignorance (Tamas) --- deluder of the living entity (Jeev)--- is born of inertia. Tamas binds Jeev by carelessness, laziness, and excessive sleep. (14.08)"
