One can understand the existence of the absolute truth by the expansion of its potencies.
“The Absolute contains multipotencies, as stated in the Vedas (Śvetāśvatara Upaniṣad): parāsya śaktir vividhaiva śrūyate. The Absolute Truth is not śakti, or energy, but śaktimān, the possessor of innumerable potencies. According to Śrīla Śrīdhara Svāmī, one should submissively hear these authorized descriptions of the Absolute Truth. As stated in the previous verse, yathānalam arciṣaḥ svāḥ: the insignificant sparks of a fire have no power to illuminate the blazing fire, which is itself the source of illumination. Similarly, the tiny living entity, who is like a spark of the Supreme Personality of Godhead, cannot illuminate the Personality of Godhead by his insignificant intellectual power. One may argue that the sun expands its potency in the form of its rays and it is through the illumination of those rays that we are able to see the sun. In the same way, we should be able to perceive the Absolute Truth by the expansion of its potency. In answer to this it may be stated that if the sun creates a cloud covering the sky, then despite the presence of sun rays the sun cannot be seen. Therefore, ultimately the power to see the sun depends not only on the sun’s rays but on the presence of a clear sky, which is also an arrangement by the sun. Similarly, as stated in this verse, one can understand the existence of the Absolute Truth by the expansion of its potencies.
atas tad apavādārthaṁ bhaja sarvātmanā harim
paśyaṁs tad-ātmakaṁ viśvaṁ sthity-utpatty-apyayā yataḥ
“You should always know that this cosmic manifestation is created, maintained and annihilated by the will of the Supreme Personality of Godhead. Consequently, everything within this cosmic manifestation is under the control of the Lord. To be enlightened by this perfect knowledge, one should always engage himself in the devotional service of the Lord.” (Bhāg. 4.29.79) As stated here, bhaja sarvātmanā harim: one must worship the Supreme Personality of Godhead so that one’s consciousness will become clean and pure, just like the clear blue sky in which the potent sun is fully manifest. When one sees the sun, he immediately sees the sun’s rays in full potency. Similarly, if one engages in the devotional service of Kṛṣṇa, one’s mind becomes cleansed of material dirt, and thus he can see not only the Lord but the Lord’s expansions as the spiritual world, as the pure devotees, as the Paramātmā, as the impersonal Brahman effulgence and as the subsequent creation of the material world, the shadow of the kingdom of God (chāyeva), in which so many material varieties become manifest.”
