When negativity takes over your mind and makes you feel tensed. The only solution is to write positives of that person.
Take some oil in a glass and place the glass in a big bowl.
Then take some coloured water and start adding the coloured water to the glass of oil.
As more water is added the oil will falls away
The glass will be full of just the coloured water
Oil is more dense (Heavier) than water so it floats on water. So when the poured amount of water in the glass increases, all the oil will finally flow out.
Water = Positivity
Oil = Negativity
The oil represents, Negativity in the mind about someone or some situation.
The coloured water represents Positivity.
As more water (positivity) is added to the oil (negativity), the oil ( negativity) will fall away and the mind will be full of just the coloured water- just positivity!
