Consecration literally means to make sacred. In yoga this means doing an act as an offering to the Divine and with the Divine as the central reference. Instead of relying on and being moved by the normal human impulses, understanding and will, one seeks contact with the soul deep within and acts from that center with its guidance. In effect one suspends and offers up one's own impulses, feelings, understanding and will power so that a higher impulsion, truer knowledge and more powerful will can act through one. By this means the seeker gradually comes more in contact with the Divine and the Divine enters into and takes hold of his entire inner life and all his outer circumstances.
Consecration leads to complete surrender and communion.
Still a man must act in the world. When an act is fully consecrated it brings to bear a far greater power of Consciousness than mind or prayer can generate. In so far as one resorts to prayer or consecration, these methods grow in power beyond the human level and bring in the dynamism of the higher consciousness. When an act is consecrated, it is no longer necessary to say that life responds to us. Rather it can be said that the Divine in life responds to the inner effort.
