Indeed, there are many means of attaining this unity. It may be done through aspiration, or surrender, or some other method. Each followed with persistence and sincerity leads to it. Aspiration is the dynamic push of your whole nature behind the resolution to reach the Divine. Surrender, on the other hand, may be defined as the giving up of the limits of your ego. To surrender to the Divine is to renounce your narrow limits and let yourself be invaded by it and made a centre for its play. But you must bear in mind that the universal consciousness so beloved of Yogis is not the Divine: you can break your limits horizontally if you like, but you will be quite mistaken if you take the sense of wideness and cosmic multiplicity to be the Divine. The universal movement is after all a mixture of falsehood and truth, so that to stop there is to be imperfect; for, you may very well share the cosmic consciousness without ever attaining the transcendent Truth. On the other hand, to go to the Divine is also to attain the universal realisation and yet remain free of falsehood.
