Rādhārāṇī is hari-priyā, very dear to Kṛṣṇa. So if we approach Kṛṣṇa through Rādhārāṇī, through the mercy of Rādhārāṇī, then it becomes very easy. If Rādhārāṇī recommends that “This devotee is very nice,” then Kṛṣṇa immediately accepts, however fool I may be. Because it is recommended by Rādhārāṇī, Kṛṣṇa accepts. Therefore in Vṛndāvana you’ll find all the devotees, they’re chanting more Rādhārāṇī’s name than Kṛṣṇa’s. Wherever you’ll go, you’ll find the devotees are addressing, “Jaya Rādhe.” You’ll find still in Vṛndāvana. They are glorifying Rādhārāṇī. They’re more interested, worshiping Rādhārāṇī. Because however fallen I may be, if some way or other I can please Rādhārāṇī, then it is very easy for me to understand Kṛṣṇa.
The devotees of the Lord in Vaikuntha want to see the Lord as most beautiful, but the devotees in Vrindavana want to see Radharani as even more beautiful than Krishna
