The totke or simple process involving water in copper vessel to overcome worry and distress is not part of any scriptures in Hinduism. But these simple processes have been followed by Hindus from ancient times and they are very effective.
Take a copper vessel and fill it with water.
Put some red sandalwood paste in it and stir the water.
Keep this safely near the head while sleeping.
In the morning, wake up at sunrise, take the water, and pour it under a tulsi plant.
When this is repeated continuously you will find relief from worry and distress.
