Sri Brahma Samhita
Chapter V - The HYMNS of LORD BRAHMA
tat-patrani sriyam api
tat--of that (lotus); kinjalkam--the petals; tat-amsanam--of His (Krsna's) fragmental portions; tat--of that (lotus); patrani--the leaves; sriyam--of the gopis (headed by Srimati Radharani); api--also.
The whorl of that eternal realm Gokula is the hexagonal abode of Krsna. Its petals are the abodes of gopis who are part and parcel of Krsna to whom they are most lovingly devoted and are similar in essence. The petals shine beautifully like so many walls. The extended leaves of that lotus are the gardenlike dhama, i.e. spiritual abode of Sri Radhika, the most beloved of Krsna.
The transcendental Gokula is shaped like the lotus. The eternal world is like a hexagonal figure; in that the entities Sri Radha-Krsna, appearing in the form of a mantra consisting of eighteen transcendental letters, are centered. The propagating manifestations emanating from the cit potency are present there with the said entities as the center. Sri Radha-Krsna is the primary cause or the seed Himself. Gopala-tapani says, "Omkara" signifies the All-Powerful Gopala and His potency; and "klim" is the same as omkara. Hence kama-bija or the primary cause of all-love, is connotative of the entities Sri Radha-Krsna.
