Today the food you eat, water you drink and air you inhale are all polluted.
People themselves are highly polluted because their minds are filled with negative feelings and worldly desires.
No doubt, you can have desires, but they should be under limits. Many human hearts are a den of evil qualities like anger, hatred, greed, jealousy, pomp and show.
Love alone can drive away these negative qualities. Desire, anger, greed, jealousy, etc., arise only out of body attachment and improper food habits.
So control your attachment and desires.
The letters that you write will appear blue when the pen is filled with blue ink and red when it is filled with red ink.
Similarly all that you see, hear and say will be negative if your heart has negative feelings.
Hence fill your heart with love. Then all that you see, hear, say and do will be suffused with love and you will experience a world suffused with love.
“There is a polish for everything that takes away rust,
and the polish for the heart is the remembrance of God.”
