When you have children, you realize how easy it is to not see them fully, and perhaps miss all those early years. If you are not careful, you can be too absorbed in work, and they will be only too happy to tell you about it later. Being a parent is one of greatest mindfulness practices of all.
In Asian languages, the word for 'mind' and the word for 'heart' are same. So if you're not hearing mindfulness in some deep way as heartfulness, you're not really understanding it. Compassion and kindness towards oneself are intrinsically woven into it. You could think of mindfulness as wise and affectionate attention.
