...that question has come to my mind several times lately.
One Buddhist monk used to ask that question frequently: "You meditate for couple of hours every day, what do you do for the rest of the day?"
"Well", I said, "Go to work, read, write, do research".
"For whom or what purpose?", he persisted.
"One must make a living", I replied
"True", he laughed, "Very true!"
That question came to my mind when I thought about the bigger Universe with all its organic and inorganic beings and creatures inside, and where all our consciousnesses go constantly through each other and overlap and influence each other.
Indeed: "What do you do for the rest of the day?"
