I also just learnt that Srimati Radhika was Sri Krishnas advisor and childhood friend. What a wonderful holy relationship !
Rādhā, is one year older to Kṛṣṇa. After Her birth, She did not open eyes for one whole year. Her parents (Vriśbhānu Mahārāj and Kirtī
were worried that something is wrong with their Girl.
Nanda Mahārāj, the father of Kṛṣṇa and Vriśbhānu Mahārāj, the father of Rādhā, were old time friends.
After Kṛṣṇa was born a year later, one day, Nanda Mahārāj and Yaśodā came to visit Vriśbhānu Mahārāj and Kirtī at their home.
Baby Kṛṣṇa crawled around in their house. Crawling, He reached the room where Rādhā was lying in a cradle. Helped Himself up, taking support of the cradle, He looked inside the cradle.
It was then, first time in one year after birth, that Rādhā opened Her big beautiful eyes. The first thing She opened Her eyes to and saw, was the beautiful face of Her beloved - Kṛṣṇa.
