Both are one. When you have love and devotion for Sri Aurobindo it automatically goes to the Mother and when you pray to the Mother it automatically goes to Sri Aurobindo as well. They are one in two bodies.
The difference is subtle and in their action. Sri Aurobindo works through the mind lifting the consciousness towards the higher realms. The Mother works through the heart bringing down the Divine into our mind, heart, life and body to transform them. It is for this reason that Sri Aurobindo has pointed out the key role of The Mother in the yoga of transformation.
It is perfectly fine to turn towards both one by one. When the time comes and the consciousness is ready, it spontaneously knows that the two are one and opens and gives itself to The Mother.
Affectionately,
