u have heard it said that a sad saint is a bad saint. Meditation is about making us happy. The happier we r the more we feel Gods presence and visa versa. i am very skeptical about people who feel and talk to God but do not exhibit that joy and happiness in relation to others or do not express love in ther encounters with others. However i think Yoshi was just saying that you can experience God in suffering as well. Because life does bring suffering as well as joy.

i done forgot the name...but there was a 'crying saint'. 
meditation also is a healer. we heal ourselves....learn to love ourselves....and connect to God again. during the period of healing , includes healing of past....sometimes during that time past 'hurts' surface,,,they do this so that we may heal and move on. 'sadness' sometimes comes during this time....it will pass.
a person may seem sad on the outside...but may not be experiencing it inside....
