Bringing down higher things by aspiration

Q: When my consciousness is in silence I try to keep my mind as empty as possible. Then I leave my sadhana and even the thought of it to the Mother. Is it O.K., or is it necessary to think of the transformation and aspire for the bringing down of the higher things?

If you can very quietly and silently aspire for the bringing down of the higher things, it might be good — but not, if it disturbs the silence.

– Sri Aurobindo
