Śrī Caitanya Mahāprabhu continued, “ ‘O my Lord, O unconquerable one, O master of all potencies, please exhibit Your internal potency to conquer the nescience of all moving and inert living entities. Due to nescience, they accept all kinds of faulty things, thus provoking a fearful situation. O Lord, please show Your glories! You can do this very easily, for Your internal potency is beyond the external potency, and You are the reservoir of all opulence. You are also the demonstrator of the material potency. You are also always engaged in Your pastimes in the spiritual world, where You exhibit Your reserved, internal potency, and sometimes You exhibit the external potency by glancing over it. Thus You manifest Your pastimes. The Vedas confirm Your two potencies and accept both types of pastimes due to them.’ ”
This verse is taken from Śrīmad-Bhāgavatam (10.87.14). It is from the prayers of the śruti-gaṇa, the personified Vedas, who glorify the Lord.
The almighty Personality of Godhead has three potencies — internal, external and marginal. The conditioned souls, who are condemned due to their forgetfulness of the Lord, are put under the control of the external potency when she creates the material world. The three modes of material nature keep the living entity in a constant state of fear (bhayaṁ dvitīyābhiniveśataḥ). The conditioned soul is always fearful due to being controlled by the external potency; therefore the conditioned soul should always pray to the almighty Lord to conquer the external potency (māyā) so that she will no longer manifest her powers, which bind all living entities, moving and inert. By praying in this way one will become eligible to remain constantly in the association of the Lord, thus fulfilling the mission of going back home, back to Godhead.
