Swamiji on Yoga

Freedom of the soul is the goal of all Yogas

From Complete Works of Swami Vivekananda, Volume I, Book: Karma Yoga—

You must remember that freedom of the soul is the goal of all Yogas, and each one equally leads to the same result. By work alone men may get to where Buddha got largely by meditation... Liberation means entire freedom — freedom from the bondage of good, as well as from the bondage of evil. A golden chain is as much a chain as an iron one. There is a thorn in my finger, and I use another to take the first one out; and when I have taken it out, I throw both of them aside; I have no necessity for keeping the second thorn, because both are thorns after all. So the bad tendencies are to be counteracted by the good ones, and the bad impressions on the mind should be removed by the fresh waves of good ones, until all that is evil almost disappears, or is subdued and held in control in a corner of the mind; but after that, the good tendencies have also to be conquered. Thus the "attached" becomes the "unattached". Work, but let not the action or the thought produce a deep impression on the mind. Let the ripples come and go, let huge actions proceed from the muscles and the brain, but let them not make any deep impression on the soul.

One does not necessarily need to practice all types of Yogas to attain perfection

From Complete Works of Swami Vivekananda, Volume I, Book: Karma Yoga—

Each one of our Yogas is fitted to make man perfect even without the help of the others, because they have all the same goal in view. The Yogas of work, of wisdom, and of devotion are all capable of serving as direct and independent means for the attainment of Moksha. "Fools alone say that work and philosophy are different, not the learned." The learned know that, though apparently different from each other, they at last lead to the same goal of human perfection.

Non-attachment is the basis

From Complete Works of Swami Vivekananda, Volume I, Book: Karma Yoga—

Without non-attachment there cannot be any kind of Yoga. Non-attachment is the basis of all the Yogas. The man who gives up living in houses, wearing fine clothes, and eating good food, and goes into the desert, may be a most attached person. His only possession, his own body, may become everything to him; and as he lives he will be simply struggling for the sake of his body. Non-attachment does not mean anything that we may do in relation to our external body, it is all in the mind. The binding link of "I and mine" is in the mind. If we have not this link with the body and with the things of the senses, we are non-attached, wherever and whatever we may be. A man may be on a throne and perfectly non-attached; another man may be in rags and still very much attached. First, we have to attain this state of non-attachment and then to work incessantly.
