If you chant one round in Vrindavan it is equal to chanting 100 rounds outside. It is not just one-sided though. You have to remember that if you make a mistake here, it is also 100 times. If you perform a sinful activity here, then there is no solution for that. You must suffer heavily. If you do some mistake here it implicates you heavily. If you do something good here then you will benefit.
