What goes around, comes around
Sadguru Speaks - Ringing the bell and offering flowers to an idol will not lessen the effect of bad deeds you have committed in the past. As you sow, so shall you reap.
Please do bear in mind - if you are prone to road accidents often or have been at the receiving end of bad news often, remember to break a coconut in your deity's presence on Sundays and Tuesdays. Leave the coconut pieces for birds to eat. Your problems will soon be resolved.
