Sometimes meditation helps but you really have to concentrate.

None of the Buddhists I know claim NIRVANA is fun. Personally, I cherish my linear memory and reasoning upon all thoughts for utility, fun, music, imagery and sacred love. Dialectics can lead to enjoyment. Finding a balanced path towards knowing thy self ones mentors ones values and priorities might be encapsulated as a VISION. PERHAPS you read Maslow or Robin Morgan ? Self actualization and following rules for radicals is a maturity of urges, purpose and Feminist inheritance. I am 67 not yet enjoying aging or living alone in retirement.....I do find communicating with my 2 Service Cats Kiti6&Laila9 a head clearing focus. I know they were born Atheists like me and have no memory of hell threats nor heaven bribes. I observe them watching me and I observe them playing, nurturing each other and enjoying their food. They must be less thirsty licking in their water so patiently one wet tongue full a second or so for a minute compared to my instant sips or gulps. Clear your head imagining you are a cat purring or squinting eyes far out the sunlit window horizon....imagine the joy of a hummingbird lapping nectar from a flower never giving a thought to 4 wings navigating next anywhere....just be

Stop thinking?
