Once Ved Vyas Ji had completed writing the 4 Vedas, he introspected. He was not feeling supreme Bliss (Braj Ras) within him. No Vibrations of love for Radha Krishna. He was feeling like a dry desert. One Day, Narad Ji, Gurudev of Ved Vyas visited Ved Vyas's Ashram. So he asked his Guru Narad Ji, why am I feeling so dry i have already written many Big Scriptures and Books, full of Knowledge.
To that Questions, Narad Ji replied, "No Matter how much knowledge you gain or write, until you don't get love of Radhe Krishna, You will not feel satisfied”. As it is said, end of the day all we need is love. Narad Ji further said, “Now i Order You, to Write about lovely pastimes of the Radhe Krishna. These sweet pastimes will bring rain in your dry desert like Heart. Your mind will become pure.” And So Maharishi Ved Vyas, wrote Book which had pastimes of the Shri Krishna which is Shrimad Bhagwatam. At last following his Guru’s aagya, He got the Love of God. One important thing to understand here, until one don’t follow the instructions of the spiritual master, one will not be able to achieve his aim.
