Srimad Bhagavatam Canto 10, Chapter 32, Text 08

SB 10.32.8

tam kacin netra-randhrena
 hrdi krtva nimilya ca
pulakangy upaguhyaste
One gopi took the Lord through the aperture of her eyes and placed Him within her heart. Then, with her eyes closed and her bodily hairs standing on end, she continuously embraced Him within. Thus immersed in transcendental ecstasy, she resembled a yogi meditating upon the Lord.
Srila Visvanatha Cakravarti Thakura states that the seven gopis mentioned so far in this chapter are the first seven of the eight principal gopis, whose status allowed them to immediately approach Sri Krsna upon His reappearance. The acarya quotes a verse from the Sri Vaisnava-tosani that gives the names of these seven as Candravali, Syamala, Saibya, Padma, Sri Radha, Lalita and Visakha. The eighth is understood to be Bhadra. Sri Vaisnava-tosani itself quotes a verse from the Skanda Purana that declares these eight gopis to be the principal among the three billion gopis. Detailed information about the hierarchy of gopis is available in Srila Rupa Gosvami’s Ujjvala-nilamani.
The Padma Purana confirms that Sri Radha is the foremost of the gopis:
yatha radha priya visnos
 tasyah kundam priyam tatha
sarva-gopisu saivaika
 visnor atyanta-vallabha
“Just as Srimati Radharani is most dear to Krsna, Her bathing pond is similarly dear. Of all the gopis, She is the most beloved of the Lord.”
The Brhad-gautamiya-tantra also names Srimati Radharani as Krsna’s foremost consort:
devi krsna-mayi prokta
 radhika para-devata
sarva-laksmi-mayi sarva
 kantih sammohini para
“The transcendental goddess Srimati Radharani is the direct counterpart of Lord Sri Krsna. She is the central figure for all the goddesses of fortune. She possesses all attractiveness to attract the all-attractive Personality of Godhead. She is the primeval internal potency of the Lord.” (This translation is Srila Prabhupada’s English rendering of Caitanya-caritamrta, Adi 4.83.)
Additional information about Sri Radha is given in the Rg-parisista (the supplement to the Rg Veda): radhaya madhavo devo madhavenaiva radhika/ vibhrajante janesu. “Among all persons, it is Sri Radha in whose company Lord Madhava is especially glorious, as She is especially glorious in His.”
