There is no stage of the Sadhana in which works are impossible, no passage in the path where there is no foothold and action has to be renounced as incompatible with concentration on the Divine. The foothold is there always; the foothold is the reliance on the Divine, the opening of the being, the will, the energies to the Divine, the surrender to the Divine. All work done in that spirit can be made a means for the Sadhana. It may be necessary for an individual here and there to plunge into meditation for a time and suspend work for that time or make it subordinate; but that can only be an individual case and a temporary retirement. Moreover, a complete cessation of work and entire withdrawal into oneself is seldom advisable; it may encourage a too one-sided and visionary condition in which one lives in a sort of mid-world of purely subjective experiences without a firm hold on either external reality or on the highest Reality and without the right use of the subjective experience to create a firm link and then a unification between the highest Reality and the external realisation in life.
Work can be of two kinds—the work that is a field of experience used for the Sadhana, for a progressive harmonisation and transformation of the being and its activities, and work that is a realised expression of the Divine. But the time for the latter can be only when the Realisation has been fully brought down into the earth-consciousness; till then all work must be a field of endeavour and a school of experience.
