Yoga is a generic name for any discipline by which one attempts to pass out of the limits of one's ordinary mental consciousness into a greater spiritual consciousness.
While everything around me is ever changing, ever dying, there is underlying that change a living power that is changeless, that holds all together, that creates, dissolves and recreates.... For I can see in the midst of death, life persists, in the midst of untruth, truth persists, in the midst of darkness light persists.
Yoga means to bind back, unite. To bring the body and the soul together. For this reason the practice of yoga is a holy endeavor and the teaching of it to our people a very high calling.
The yoga we practice is not for ourselves alone, but for the Divine; its aim is to work out the will of the Divine in the world, to effect a spiritual transformation and to bring down a divine nature and a divine life into the mental, vital and physical nature and life of humanity. Its object is not personal Mukti, although Mukti is a necessary condition of the yoga, but the liberation and transformation of the human being. It is not personal Ananda, but the bringing down of the divine Ananda - Christ's kingdom of heaven, our Satyayuga - upon the earth.
Thus to act under the guidance coming from above, this is one side of the sadhana, the dynamic side. The other one is the discrimination between the Purusha and the Prakriti. The Purusha will calmly observe, give sanction, choose, but will realise that all this does not belong to him - all these are outside him. This is the static side of the sadhana. These two aspects constitute the basis of Yoga.
If you don't love yourself, you cannot love others. You will not be able to love others. If you have no compassion for yourself then you are not able of developing compassion for others.
