Sadhana must be the main thing and sadhana means the purification of the nature, the consecration of the being, the opening of the psychic and the inner mind and vital, the contact and presence of the Divine, the realisation of the Divne in all things, surrender, devotion, the widening of the consciousness into the cosmic Consciousness, the Self one in all, the psychic and spiritual transformation of the nature. If these things are neglected... and mental development and social contact occupy all the time, then that is not sadhana.
In our yoga we begin with the idea, the will, the aspiration of the complete surrender; but at the same time we have to reject the lower nature, deliver our consciousness from it, deliver the self involved in the lower nature by the self rising to freedom in the higher nature. If we do not do this double movement, we are in danger of making a tamasic and therefore unreal surrender, making no effort, no tapas and therefore no progress; or else we may make a rajasic surrender not to the Divine but to some self-made false idea or image of the Divine which masks our rajasic ego or something still worse.
A perfect confidence in the Divine Mother and a vigilance to repel all wrong suggestions and influences is the main law of this yoga.
A quieted mind (not necessarily motionless or silent, though it is good if one can have that at will) and a persistent aspiration in the heart are the two main keys of the yoga.
The object of the sadhana can only be to live in the divine consciousness and to manifest it in life.
Ascend from Nature to divinity's heights;
Face the high gods, crowned with felicity,
Then meet a greater God, thy self beyond Time.
This word was seed of all the thing to be.
A hand from some Greatness opened her heart's locked doors
And showed the work for which her strength was born.
