02. Synthetic Method and Integral Yoga
It is altogether unprofitable to enquire who or what class will 
arrive first or last at the goal. The spiritual path is not a field of competition or a race that this should matter. What matters is one’s own aspiration for the Divine, one’s own faith, surrender, selfless self-giving. Others can be left to the Divine who will lead each according to his nature. Meditation, work, bhakti are each means of preparative help towards fulfilment; all are included in this path. If one can dedicate oneself through work, that is one of the most powerful means towards the self-giving which is itself the most powerful and indispensable element of the sadhana.
To cleave to the path means to follow it without leaving it or turning aside. It is a path of self-offering of the whole being in all its parts, the offering of the thinking mind and the heart, the will and actions, the inner and the outer instruments so that one may arrive at the experience of the Divine, the Presence within, the psychic and spiritual change. The more one gives of oneself in all ways, the better for the sadhana. But all cannot do it to the same extent, with the same rapidity, in the same way. How others do it or fail to do it should not be one’s concern – how to do it faithfully oneself is the one thing important.
