SALT

In all civilisations, salt has been a symbol of purification and incorruptibility. It was commonly used as a conservative for food.

In the liturgy, a grain of salt was put on the baby's tongue during baptising to chase the demons.

The occult practice has exalted its virtues, making it a powerful agent of purification and protection, utilised during the rituals, to captivate the negative energies and thereby dispose of them easily thereafter.

That's why, salt was thrown, in all four cardinal directions within the house, in which a negative event had taken place, to absorb the energies and therefore purify the place.
