Emotions - Happiness, anger, jealousy... Is the mind experiencing "presence" in our existence.
Grief, I've learned, is really just love.
It's all the love you want to give, but cannot. All of that unspent love gathers in the corners of your eyes, the lump in your throat, and in the hallow part of your chest. Grief is just love with no place to go.
Routine ruins the life, variety vitalise the life.
