Kusam Sarovara

"It is said by Sri Rupa Gosvami: 'When one is actually liberated from material contamination, he can always remember an eternal devotee in Vrindavana in order to love Krsna in the same capacity. And developing such an aptitude, one will always live in Vrindavana, even within his mind.' The purport is that, if it is possible, one should go and physically be present at Brajabhumi, Vrindavana, and be engaged always in the service of the Lord, following the devotees in Brajadhama, the spiritual realm of Braja. If it is not possible, however, to be physically present at Vrindavana, one can meditate anywhere upon living in that situation. Wherever he may be, one must always think about life in Brajadhama and about following in the footsteps of a particular devotee in the service of the Lord."
