Humbly I come to you who are more advanced in the teaching to ask about laughter and its place in the conduct of a Dhamma follower. I quote the book "Mindfulness in Plain English," introduction:
Go to a party. Listen to the laughter, that brittle-tongued voice that says fun on the surface and fear underneath. Feel the tension, feel the pressure. Nobody really relaxes. They are faking it. Go to a ball game. Watch the fan in the stand. Watch the irrational fit of anger. Watch the uncontrolled frustration bubbling forth from people that masquerades under the guise of enthusiasm, or team spirit. Booing, cat-calls and unbridled egotism in the name of team loyalty. Drunkenness, fights in the stands. These are the people trying desperately to release tension from within. These are not people who are at peace with themselves. Watch the news on TV. Listen to the lyrics in popular songs. You find the same theme repeated over and over in variations. Jealousy, suffering, discontent and stress.
Is laughter right speech? Can laughter be done with metta? I am lately applying my mindfulness to that of the body/mind, and I am noticing that laughter in my body is always accompanied by a feeling of conceit or ill will. Even if I laugh at the innocent antics of a child it is still a mental process where I am placing myself above the child to compare myself to it and laugh at its foolishness or stupidity.
In my experience it is very rare to experience laughter without other harmful mental formations.
Laughter also creates a lot of noise, and draws attention.
Is it consistent with Equanimity (upekkha) to laugh?
To be unwavering or staying neutral in the face of the eight vicissitudes of life, loss and gain, good-repute and ill-repute, praise and censure, and sorrow and happiness (Attha Loka Dhamma), is to practice true upekkha.
