Life without desires is not only imaginable but also the most wonderful life one can conceive of, it is a life of peace and freedom and joy. Far from being a life of inertia, it is a life of intense, powerful action driven no more by the fossil fuel of desire and ambition, but by the clean and pure energy of the Divine Mother, the direct working of the Divine Shakti in the Adhaar that is prepared and ready than Her diminished action limited and distorted by our ego and ignorance.
But not all are ready for this direct working of the Divine hence the fuel of desire is needed to push us until we understand its limitations and are ready to go beyond it. It is a question of stage of evolution. The tamasic man is like a stone and needs strong and violent push to act, the push provided by all kinds of hungers such as food and sex. The rajasic man needs desires and ambitions to get him going. The sattwic man is moved to act under some kind of idealism even if it means sacrificing his personal ambition and desires. But the spiritual man moves by the Will of the Divine Shakti to fulfil the Divine Purpose in the world.
Affectionately,
