05. Sadhana through Work
All the difficulties you describe are quite natural things common to most people. It is easy for one, comparatively, to remember and be conscious when one sits quiet in meditation; it is difficult when one has to be busy with work. The remembrance and 
consciousness in work have to come by degrees, you must not expect to have it all at once; nobody can get it all at once. It comes in two ways,– first, if one practises remembering the Mother and offering the work to her each time one does something (not all the time one is doing, but at the beginning or whenever one can remember,) then that slowly becomes easy and habitual to the nature. Secondly, by the meditation an inner consciousness begins to develop which, after a time, not at once or suddenly, becomes more and more automatically permanent. One feels this as a separate consciousness from that outer which works. At first this separate consciousness is not felt when one is working, but as soon as the work stops one feels it was there all the time watching from behind; afterwards it begins to be felt during the work itself, as if there were two parts of oneself – one watching and supporting from behind and remembering Mother and offering to her and the other doing the work. When this happens, then to work with the true consciousness becomes more and more easy.
It is the same with all the rest. It is by the development of the inner consciousness that all the things you speak of will be set right. For instance it is a part of the being that has utsāha for the work, another that feels the pressure of quietude and is not so disposed to work. Your mood depends on which comes up at the time – it is so with all people. To combine the two is difficult, but a time comes when they do get reconciled – one remains poised in an inner concentration while the other is supported by it in its push towards work. The transformation of the nature, the harmonising of all these discordant things in the being are the work of sadhana. Therefore you need not be discouraged by observing these things in you. There is hardly anybody who has not found these things in himself. All this can be arranged by the action of the inner Force with the constant consent and call of the sadhak. By himself he might not be able to do it, but with the Divine Force working within all can be done.
