Yogas chitta vritti nirodhah - (Yoga is to check the mind from changing) - which is acceptable to all. That is also the goal of all. The method is chosen according to one's own fitness. The goal for all is the same. Yet different names are given to the goal only to suit the process preliminary to reaching the goal. Bhakti, Yoga, Jnana are all the same.
Vaire¢gya 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 Jne¢ni (philosopher) renounces everything, because his philosophy is that Nature never existed, neither in the past, nor present, nor will It in the future.
