An anchored line used as a support to someone who may fall or drown; a line shot to a ship in distress either to connect it with the shore or for hauling aboard other life-saving devices; lines rigged to keep the crew aboard in bad weather.
The life line is a rope that runs around the perimeter of the boat for people to hang onto so they don't fall out of the boat and possibly lose their lives (hence the name, life line). A life line is an essential boating safety accessory for any boat owner.
Life lines stem from a neuro-linguistic programming principle that in order to perform some kinds of inner exploration with full commitment, one must let go of various limits and beliefs that are needed day-to-day, and which may be dangerous or psychologically difficult to set aside.
