Mindfulness counter

Use white and black pebbles to count your thoughts and actions.

"Long ago, there was a brahmin called Ravi who examined his mind at all times. Whenever a bad thought arose, he would put aside a black pebble, and whenever a good thought arose he would put aside a white pebble. At first, all the pebbles he put aside were black. Then, as he persevered in developing antidotes and in adopting positive actions and rejecting negative ones, a time came when his piles of black and white pebbles were equal. In the end he had only white ones.

This is how you should develop positive actions as an antidote with mindfulness and vigilance, and not contaminate yourself with even the smallest harmful actions." [Words of My Perfect Teacher - Patrul Rinpoche]
