tri-pāda-vibhūti kṛṣṇera - three fourths of the energy of Lord Kṛṣṇa; vākya-agocara - beyond words; eka-pāda vibhūtira - of one fourth of the energy; śunaha - please hear; vistāra - breadth.

“The three-fourths part of Lord Kṛṣṇa’s energy is beyond our speaking power. Let us therefore hear elaborately about the remaining one fourth of His energy.
