If we chant the holy name of the Lord seriously we can see vrindavan within our heart, wherever we are.
If we hear properly, the holy name will enter through our ears into the region of our heart and shower down nectar. When we are lost in the ocean of nectar, we will see Krishna.
Chanting of the Hare Krishna maha-mantra is potent always, but it is especially potent in this Age of Kali.
Srimad Bhagavatam 8.5..23
We Should know in perfect consciousness that human life is bestowed upon the conditioned soul to achieve spiritual success and the easiest possible procedure to attain this end is to chant the holy name of the Lord. – Srimad Bhagavatam, 02.01.12.
