dui vastu bheda nai, sastra-paramana
radha—Srimati Radharani; purna-sakti—the complete energy; krsna—Lord Krsna; purna-saktiman—the complete possessor of energy; dui—two; vastu—things; bheda—difference; nai—there is not; sastra-paramana—the evidence of revealed scripture.
Sri Radha is the full power, and Lord Krsna is the possessor of full power. The two are not different, as evidenced by the revealed scriptures.
