I personally can't chant on the beads without offenses. I just perform Sankirtana, with comparatively little distraction. When I am walking, I usually sing Hare Krishna, Shopping at Walmart or Trader Joes (grocery stores), just sing through the easels. I know that I am already back to Godhead when I am singing Hare Krishna in public. In fact I feel no desire to go back to Godhead. Where ever we are, we can create a Vrindavan simply by performing Sankirtana. Then what is the need to go back to Godhead?
Why go back to Godhead, when Vrindavan can be experience right here on the Earth by performing Sankirtana while we distribute Krishna Prema freely to all.
