Watch / Witness
When we relate ourselves as strangers to an incident, we get to understand the terms, watch and witness better.
When we walk down the road, let us say we comeacross an accident taking place. As a stranger, we watch it happening. We are no way involved in the incident except as a spectator. But when the police arrive to the scene and enquire only some from the watching spectator come forward to be a witness to the incident. Its now being a part of the incident and yet not directly involved. Aware as a part of it and yet detached.
In life too, we get to play this role of watching and witnessing from moment to moment. Sometimes, its only watching which is needed and yet other times, its witnessing that happens with the activities of the world outside us. When it comes to the world within, witnessing enables us to have better clarity and awareness. We become a part of the whole and yet learn to remain detached.
