The water we drink, gets in our body and is thrown out in 4 hours, else we will fall ill.
The air we breathe, has to be thrown out in 1 minute, else we will die.
What about negative emotions like hatred, anger, jealousy, insecurity … we hold in our body for days, months and years.
If these negative emotions are not thrown out regularly it props up into psycho-somatic diseases.
And meditation and prayers are safest way to dissolve these emotions.
