Most people live in their ordinary outer ignorant personality which does not easily open to the Divine ; but there is an inner being within them of which they do not know, which can easily open to the Truth and the Light. But there is a wall which divides them from it, a wall of obscurity and unconsciousness. When it breaks down there is a release. 
The obstruction of the lower Nature or the pressure of the adverse forces can often act successfully for a time, even for a long time, against the necessary change. One has then to persist, to put always the will on the side of the Divine, rejecting what has to be rejected, opening oneself to the true Light and true Force, calling it down quietly, steadfastly, without tiring, without depression or impatience, until one feels the Divine Force at work and the obstacle beginning to give way. 
[Occultism:] The knowledge and right use of the hidden forces of Nature. 
True occultism means no more than a research into supraphysical realities and an unveiling of the hidden laws of being and Nature, of all that is not obvious on the surface. It attempts the discovery of the secret laws of mind and mental energy, the secret laws of life and life-energy, the secret laws of the subtle-physical and its energies,—all that Nature has not put into visible operation on the surface; it pursues also the application of these hidden truths and powers of Nature so as to extend the mastery of the human spirit beyond the ordinary operations of mind, the ordinary operations of life, the ordinary operations of our physical existence. 
The forces that can only be known by going behind the veil of apparent phenomena—especially the forces of the subtle physical and supraphysical planes. 
Ojas or prāṇaśakti is the primal energy which proceeds from ether. 
Om is the mantra, the expressive sound-symbol of the Brahman Consciousness in its four domains from the Turiya to the external or material plane. The mantra Om should lead towards the opening of the consciousness to the sight and feeling of the One Consciousness in all material things, in the inner being and in the supraphysical worlds, in the causal plane above now superconscient to us and, finally, the supreme liberated transcendence above all cosmic existence. 
Om if rightly used (not mechanically) might very well help the opening upwards and outwards (cosmic consciousness) as well as the descent.
