Does Life line indicate how we go through phases from Individuality to responsibility

Hello All

Iam just thinking what really could life line imply, since the begiining of life line is from conscious zone and bottom of jupiter mount and ending is in the middle zone, i was wondering whether it gives us information on how we go through a phase of our individuality and move towards to responsbility (as indicated by middle zone). The heartline indicates the movement of line from subcocnious to cosncious zone, head line from consciouszone to subconscious zone, fate line more on middle zone, so there has to be some line which provides information on relation within the conscious zone especially the two important fingers in that zone.

Thanks
