The seeker in the integral Yoga cannot deny or avoid the various powers and aspects of his being, even has he must accept and work with the forces and actions that take place in the outer world. In addition, the seeker cannot depend on the method of exclusive concentration to reduce the complexity of his process, other than for short periods of focus on a specific aspect of change that needs to occur. This brings before the seeker the entire range of divergent and opposed drives, needs and desires that operate within each of the different levels of the being, and he needs to find a way to bring them into harmony and organize them so that they all work together to achieve the ultimate spiritual realisations and transformation of the nature.
Sri Aurobindo describes the situation: “He has to harmonise deliberate knowledge with unquestioning faith; he must conciliate the gentle soul of love with the formidable need of power; the passivity of the soul that lives content in transcendent calm has to be fused with the activity of the divine helper and the divine warrior. To him as to all seekers of the spirit there are offered for solution the oppositions of the reason, the clinging hold of the senses, the perturbations of the heart, the ambush of the desires, the clog of the physical body; but he has to deal in another fashion with their mutual and internal conflicts and their hindrance to his aim, for he must arrive at an infinitely more difficult perfection in the handling of all this rebel matter. Accepting them as instruments for the divine realisation and manifestation, he has to convert their jangling discords, to enlighten their thick darknesses, to transfigure them separately and all together, harmonising them in themselves and with each other,–integrally, omitting no grain or strand or vibration, leaving no iota of imperfection anywhere. An exclusive concentration, or even a succession of concentrations of that kind, can be in his complex work only a temporary convenience; it has to be abandoned as soon as its utility is over. An all-inclusive concentration is the difficult achievement towards which he must labour.”
