Sitting on a pillow is for you to develop and grow. The more you develop and grow, then hopefully the more you are going to be of benefit for others. It's very simple, for example, a kid goes to school wanting to be a doctor, there's 12 years of regular education, still wants to be a doctor, then three or four years of university, still wants to be a doctor, goes to medical school, still wanting to be a doctor, finally ends up being a doctor. All that time, all those years spent on developing themselves, so that one day they can help others. So, sitting on a pillow is very much for you to help develop yourself, develop that Compassion/Lovingkindness wish so strongly that it will come up throughout the day, anywhere you are, with whomever you are with.
