nocet pramattam asad-indriya-vaji-suta
nitvotpatham visaya-dasyusu niksipanti
te dasyavah sahaya-sutam amum tamo 'ndhe
samsara-kupa uru-mrtyu-bhaye ksipanti
Otherwise, if one does not take shelter of Acyuta and Baladeva, then the senses, acting as the horses, and the intelligence, acting as the driver, both being prone to material contamination, inattentively bring the body, which acts as the chariot, to the path of sense gratification. When one is thus attracted again by the rogues of visaya -- eating, sleeping and mating -- the horses and chariot driver are thrown into the blinding dark well of material existence, and one is again put into a dangerous and extremely fearful situation of repeated birth and death.
Without the protection of Gaura-Nitai -- Krsna and Balarama -- 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 Nitai-Gaura, or Krsna-Balarama. Without the mercy of Nitai-Gaura, there is no way to come out of this dark well of ignorance. As stated in the Caitanya-caritamrta (Adi 1.2):
citrau sandau tamo-nudau
"I offer my respectful obeisances unto Sri Krsna Caitanya and Lord Nityananda, who are like the sun and moon. They have arisen simultaneously on the horizon of Gauda 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-Nitai, 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.
