Work for the Mother and Sadhana
Work for the Mother done with the right concentration on her is as much a Sadhana as meditation and inner experiences.
Those who do work for the Mother in all sincerity are prepared by the work itself for the right consciousness even if they do not sit down for meditation or follow any particular practice of Yoga. It is not necessary to tell you how to meditate; whatever is needful will come of itself, if in your work and at all times you are sincere and keep yourself open to the Mother.
