World Honored One (Buddha) at one time posed a question to his disciples and followers at a Dharma assembly, He asked 'How long is a human's life span?'
Some answered, as long as the day, some say as long as the night. Some say around 70 years, some say around 80 years, some say it depends on karmic forces, some say it depends on how one conditions one's health and eating habits.
The Buddha answered by pointing his finger to his nose, "The length of a human's life span is in his breath..."
Life is but a collection of fleeting moments of the six kinds of sensations. Inhale, Exhale... Dreaming.... when will I wake up?
