Without the protection of Gaura-Nitāi—Kṛṣṇa and Balarāma—one cannot get out of the dark well of ignorance in material existence. This is indicated here by the word nocet, which means that one will always remain in the dark well of material existence. The living entity must get strength from Nitāi-Gaura, or Kṛṣṇa-Balarāma. Without the mercy of Nitāi-Gaura, there is no way to come out of this dark well of ignorance. As stated in the Caitanya-caritāmṛta (CC.1:1:2):

vande śrī-kṛṣṇa-caitanya-
nityānandau sahoditau
gauḍodaye puṣpavantau
citrau śandau tamo-nudau
"I offer my respectful obeisances unto Śrī Kṛṣṇa Caitanya and Lord Nityānanda, who are like the sun and moon. They have arisen simultaneously on the horizon of Gauḍa to dissipate the darkness of ignorance and thus wonderfully bestow benediction upon all." This material world is a dark well of ignorance. The fallen soul in this dark well must take shelter of the lotus feet of Gaura-Nitāi, for thus he can easily emerge from material existence. Without Their strength, simply attempting to get out of the clutches of matter by speculative knowledge will be insufficient.
