All meditation must begin with arousing deep compassion. Whatever one does must emerge from an attitude of love and benefitting others.
MilarepaWhen you run after your thoughts, you are like a dog chasing a stick: every time a stick is thrown, you run after it. Instead, be like a lion who, rather than chasing after the stick, turns to face the thrower. One only throws a stick at a lion once.
