Detachment is not indifference. it is the prerequisite for effective involvement. Often what we think is best for others is distorted by our attachments to our opinions. We want others to be happy in the way we think they should be happy. It is only when we want nothing for ourselves that we are able to see clearly into others needs and understand how to serve them.
Meditation brings wisdom; lack of meditation leaves ignorance. Know well what leads you forward and what holds you back, and choose the path that leads to wisdom.
Who cares for your bhakti and mukti? Who cares what your scriptures say? I will go into a thousand hells cheerfully if I can rouse my countrymen, immersed in tamas, to stand on their own feet and be men inspired with the spirit of karma-yoga. I am a follower only of he or she who serves and helps others without caring for his own bhakti and mukti!
Without going outside, you may know the whole world, without looking through the window, you may see the ways of heaven. The farther you go, the less you know. Thus the sage knows without traveling; he sees without looking; he works without doing.
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.
One must know oneself as one is, not as one wishes to be, which is merely an ideal and therefore fictitious, unreal; it is only that which is that can be transformed, not that which you wish to be.
The higher Truth is all the time working in us but through the lower power - Aparashakti. It is when we become conscious of the play of this higher Power then only yoga begins.
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.
