a) Control the mind and perform namakeerthanam if you can
b) Let the mind run helter-skelter, perform namakeerthanam
c) Give the control-of-mind responsibility to Sri Ranganathar, perform namakeerthanam
ANY WAY, FOR THE ONE PERFORMING NAMAKEERTHANAM, HE WILL NEVER PERISH. "namE bhakthaHa pranishyathi".
