It is said that Sri Radha is herself the "Devotional energy" of Lord Shri Krishna who is the Lord of the universe. Her name always comes before the name of Lord Krishna that is why God's one name is "Radha Krishna" also. Just take out only one "R" from "Radha Krishna" & it becomes just "half Krishna" & that is the power of the name "Radha".
"Shyama" is another name of Shri Radha.
"Meri bhav badha haro, Radha nagari soey,
Ja tan ki jhaien parat, Shyam Harit duti hoey."
Hey, Goddess Shri Radha, You take care of my life of all troubles, Who's body shadow is enough to make Lord Krishna happy.
This bhajan is sung by "Shri Baldev Krishan" who generally accompany Shri Vinod Aggarwal Ji. Shri Baldev Krishan Ji too have a great devotion towards Shri Radha Krishna.
Jai Shri Radhe Krishna. I love this Bhajan the most.
