During the introductory ten-day SN Goenka silent meditation courses, students are told they should practice for an hour in the morning and an hour in the evening every day. Having no experience with other forms of meditation, I was under the impression that I had to do this in order to achieve good results.
In the winter I have a morning meditation. It starts in October and ends in April. It is one I have to do in the morning whether I like it or not, more to the case whether I want to be warm or not. Before morning tea or toast with sleep still in my eyes I must create fire.
I've been meditatiing for a few months and have been having an increasingly common problem after meditation sessions. I meditate for about 20 minutes in the morning and then afterwards feel real spacey until late afternoon. I have a hard time engaging in conversation, although my ability to concentrate is very good. There seems to be a disconnect between thought and speech. Also there is a physical sensation almost like a headache, sort of like my head is stuffed with cotton.
"A Sangha is a community of resistance, resisting the speed, violence and unwholesome ways of living that are prevalent in our society. Mindfulness is to protect ourselves and others. A good Sangha will lead us in the direction of harmony and awareness. The substance of the practice is most important. The forms can be adapted." ~ Thich Nhat Hahn
