The integral Yoga does not just give “lip-service” to non-duality; rather it takes up this concept and implements it by refusing to accept a lesser reality, or any kind of “unreality” to the manifested universe. The solution to the riddle of life is not to abandon life, but to fulfill it to its highest significance and greatest potential, as the intentional rolling out of the Will of the Supreme in its self-manifestation through the evolutionary process. The key idea is “reality omnipresent” and the implementation is carried out through the conversion of all thoughts, emotions, and actions as a dedicated action of Yoga.
To accomplish this, a total change of standpoint is required, so that the seeker is able to live in the Knowledge, based on this ultimate Oneness, rather than the Ignorance which fixates on the artificial division and fragmentation that we see through our human mental understanding.
“But its first condition for this liberality is that our works in the world too must be part of the sacrifice offered to the Highest and to none else, to the Divine Shakti and to no other Power, in the right spirit and with the right knowledge, by the free soul and not by the hypnotised bondslave of material Nature.”
“…all activities of knowledge that seek after or express Truth are in themselves rightful materials for a complete offering; none ought necessarily to be excluded from the wide framework of the divine line. The mental and physical sciences which examine into the laws and forms and processes of things, those which concern the life of men and animals, the social, political, linguistic and historical and those which seek to know and control the labours and activities by which man subdues and utilises his world and environment, and the noble and beautiful Arts which are at once work and knowledge,–for every well-made and significant poem, picture, statue or building is an act of creative knowledge, a living discovery of the consciousness, a figure of Truth, a dynamic form of mental and vital self-expression or world-expression,–all that seeks, all that finds, all that voices or figures is a realisation of something of the play of the Infinite and to that extent can be made a means of God-realisation or of divine formation. But the Yogin has to see that it is no longer done as part of an ignorant mental life; it can be accepted by him only if by the feeling, the remembrance, the dedication within it, it is turned into a movement of the spiritual consciousness and becomes a part of its vast grasp of comprehensive illuminating knowledge.”
