Commitment is not complicated. Commitment to another person is being there for that person in mind, body and spirit, when being there for that person is needed and wanted by that person. It is not simply hanging around in a prespecified role and half-heartedly going through the motions. In too many cases. this is called 'marriage' or 'family'.
Commitment is a living, creative and conscious decision. It is not a name on a deed or a bank account. In these materialistic times, commitment is confused with financial contract. They are not the same. The financial contract may indeed be a mutually decided upon symbol of an ongoing commitment. However, the commitment itself is only as good as its regular renewal and verification by those partnered in it.
My practice involves serious maintenance and clarification of commitments. This is a process, alive in the present in each relationship which entails commitment. In an existential sense, every transaction in my life entails an openness on my part to commitment to honest and compassionate interaction. This applies to daily business transactions, contacts with strangers and contacts within my social network. When a society maintains this kind of practice, it is considered truly civilized.
