Restlessness in meditation is a serious obstacle which should be dealt with and adequate strategy. A strategy of war. Unfortunately, a busy life favours restlessness. Being retired would be a definite advantage. But Satan is working to avoid that. In my country retirement age is swifting upward evermore.
Your use of the word Satan interests me. i usually use the word maya to describe a similar energy. But the use of 'Satan' seems to really personalize this evil that often controls people or tempts us to do things we would not normaly do if it wasnt for the enticing nature that allures us.
