Swami Vivekananda said this quote

Vairâgya or renunciation is the turning point in all the various Yogas. The Karmi (worker) renounces the fruits of his work. The Bhakta (devotee) renounces all little loves for the almighty and omnipresent love. The Yogi renounces his experiences, because his philosophy is that the whole Nature, although it is for the experience of the soul, at last brings him to know that he is not in Nature, but eternally separate from Nature. The Jnâni (philosopher) renounces everything, because his philosophy is that Nature never existed, neither in the past, nor present, nor will It in the future.
