What you have to aspire for most is the improved quality of the recipient consciousness in you, discrimination in the mind, the unattached impersonal Witness look on all that goes on in you and around you, purity in the vital, calm equanimity, enduring patience, absence of pride and the sense of greatness — and more especially, the development of the psychic being in you — surrender, self-giving, psychic humility, devotion. It is a consciousness made up of these things, cast in this mould, that can bear without breaking, stumbling or deviation into error the rush of lights, power and experiences from the supraphysical planes.
The things that have to be established are — complete sex purity; quiet and harmony in the being, its forces maintained but controlled, harmonised, disciplined; truth and sincerity in the whole nature; a general state of peace and calm; the power and habit to control whatever needs control in the movements of the nature. When these are fairly established, one has laid a foundation on which one can develop the yogic consciousness and with the yogic consciousness there comes an easy opening to realisation and experience.
I am thy portion here charged with thy work,
As thou myself seated for ever above,
Speak to my depths, O great and deathless Voice,
Command, for I am here to do thy will.
