On the occasion of the Feast of the Baptism of the Lord, there are numerous prohibitions, most of which pertain to water. The website "Closer to God" shared various traditions and customs related to the celebration.
Mix holy water with regular water
On this day, holy water possesses special power, and mixing it with regular water will cause it to lose its properties. Many do this to increase the quantity of water, but it is strictly prohibited on the day of the Baptism.
Pour holy water down the sink
Holy water should be treated with respect. If it needs to be disposed of, it is better to pour it onto the ground in a clean place.
Show disrespect towards holy water
It is believed that one should not drink it without reverence or use it with disbelief.
Curse and argue near the water
Superstitions suggest that water absorbs the energy of its surroundings, and any negative behavior can affect its properties.
Swim in a hole without preparation
If you wish to immerse yourself in the blessed water, it is important to follow safety rules. Swimming without preparation can be hazardous to one's health.
Do laundry
This is one of the main prohibitions related to water on this day. Doing laundry is considered an irreverent act towards water today.
Do not use holy water for magic
Believers hold holy water in high regard as particularly blessed. Using it for magic, witchcraft, or other unholy practices is a violation of the sanctity of this rite.
