My question to your question is: How can your practice be shallow? How deep is deep? Do we touch the bottom of the ocean and say "Ok! Deep enough!" or do we dig even further towards to Earth's core? Even then, we only touch our planet. This moment greets you with open arms, the entire world says "Here I am! This is it!" So what do you do?
Children, college, raucous holiday parties, friends, enemies. What more can you have than this moment? It would be arrogant of me and my 19 years to say that I understand life, but I'm working on greeting it at the door a much as I can.
