The Divine Mother is the original Power, Adya Shakti. If we invoke Her then She does what is needed, gives or takes away whatever is necessary in Her total vision. Nothing more is then needed since She is the Mother of the gods and whatever She grants, the others are compelled to concede. There is no need to invoke different deities once one invokes the Divine Mother. If anything it is likely to create confusion by interfering in a more comprehensive action of the Divine Mother.
Affectionately,
