During meditation you take a dive into the transcendent. Then the transcendent is integrated into your physiology during activity. So both meditation and activity are important aspects of your evolution. Retreats are designed so you can take a deeper and longer dive into the transcendent twice a year. It is like nature. The sun rises and sets every day. There is also the larger cycle of the four seasons. During retreats it is best to not engaged too much into your business or other worldly matters. Just do your best to stay with the program and enjoy.
