Out of many such learned scholars and philosophers, one who is actually liberated from material bondage is better, and out of many such persons who are actually liberated, one who is a devotee of the Supreme Personality of Godhead is considered to be the best. Among the many such transcendental lovers of the Supreme Personality of Godhead, the gopīs are the best, and among the gopīs Śrīmatī Rādhikā is the best.

Their second business is to gradually create a situation in which the hero may be attracted to the heroine and vice versa. Their third business is to induce both of Them to approach each other. Their fourth business is to surrender unto Kṛṣṇa, the fifth is to create a jovial atmosphere, the sixth to give Them assurance to enjoy Their pastimes, the seventh to dress and decorate both hero and heroine, the eighth to show expertise in expressing Their desires, the ninth to conceal the faults of the heroine, the tenth to cheat their respective husbands and relatives, the eleventh to educate, the twelfth to enable the hero and heroine to meet at the proper time, the thirteenth to fan the hero and heroine, the fourteenth to sometimes reproach the hero and heroine, the fifteenth to set conversations in motion, and the sixteenth to protect the heroine by various means.

nayasi katham ihāsmān dustyaja-dvandva-pārśvaṁ

satatam urasi saumya śrīr vadhūḥ sākam āste

"You are Kṛṣṇa's very dear friend, and by His order you have come here again. Therefore you are worshipable for Me. O best of messengers, tell Me now, what is your request? What do you want? Kṛṣṇa cannot give up conjugal love, and therefore I understand that you have come here to take us to Him. But how will you do that? We know that many goddesses of fortune now reside at Kṛṣṇa's chest, and they constantly serve Kṛṣṇa better than we can."

Teachings of Lord Caitanya

Teachings of Lord Caitanya, Chapter 1:

Regarding the dealings of the gopīs with Sri Kṛṣṇa in Vṛndāvana, it is described (SB 10.30.36-40) that when Sri Kṛṣṇa took Śrīmatī Rādhikā alone from the rāsa dance, She thought that Kṛṣṇa had left all the other gopīs. Although they were all equally beautiful, He satisfied Her in this way, and She began to think proudly, "My dear Lord Kṛṣṇa has left the beautiful gopīs, and He is satisfied with Me alone." In the forest, She told Kṛṣṇa, "My dear Kṛṣṇa, I am unable to move anymore. Now if You like You can take Me wherever You desire." Kṛṣṇa replied, "Come lean against My shoulder," and as soon as He said this, He disappeared, whereupon Śrīmatī Rādhikā repined greatly.

When Kṛṣṇa disappeared from the scene of the rāsa dance, all the gopīs began to repent, saying, "Dear Kṛṣṇa! We have come here and have left aside our husbands, sons, relatives, brothers and friends! Neglecting their advice, we have come to You, and You best know the reason for our coming here. You know that we have come because we are captivated by the sweet sound of Your flute. But You are so cunning that in the dead of night You have left girls and women like us! This is not very good for You."

Teachings of Lord Caitanya, Chapter 6:

There is a passage in the Fourth Chapter of the Lalita-mādhava (4.19), in which Kṛṣṇa addresses Uddhava as follows: "My dear friend, the form of Govinda, the cowherd boy, attracts Me. Indeed, I wish to be like the damsels of Vraja, who are also attracted by this form of Govinda." Similarly, in the Eighth Chapter, Kṛṣṇa says: "O how wonderful it is! Who is this person? After seeing Him, I am so attracted that I am now desiring to embrace Him just like Rādhikā."

Teachings of Lord Caitanya, Chapter 31:

In Govinda-līlāmṛta there is a verse which states: "Who is the breeding ground for Kṛṣṇa's affection? The answer is that it is only Śrīmatī Rādhikā. Who is Kṛṣṇa's most lovable object? The answer is that it is only Śrīmatī Rādhikā and no one else." Sheen in the hair, moisture in the eyes and firmness in the breasts are all qualities present in Śrīmatī Rādhikā. Only Śrīmatī Rādhikā is able to fulfill all the desires of Kṛṣṇa. No one else can do so.
