Also called: Inner Life Line · Sister Line of Life · Vita Soror · Linea Martis · Guardian Angel Line

Where on the hand: A line running INSIDE the Life line — between the Life line and the thumb, on the Mount of Venus side — parallel to it and close beside it. It rises from the Mount of Lower Mars (the small area inside the Life line's origin, in the thumb-web) and runs down alongside the Life line, either partway or its whole length. Indian sources add a second course: rising from the lower Mars area or the early part of the Life line and running toward the Venus mount rather than parallel to the Life line.

What it looks like: A fine to deep sister-line hugging the Life line's inner curve; may be short or full-length, and several Mars lines of differing thickness may appear on one palm.

The vitality-reserve line — a line of reinforcement. It shows great vitality, power of resistance to illness and disease, and constitutional strength greater than even a deep Life line shows. It carries courage, fighting spirit and a robust, combative disposition. Above all it is protective: it minimises and bridges breaks in the Life line.

Western reading: Benham and the classical writers treat it as the sister line of Life — a reserve of vitality and combativeness that repairs Life-line breaks. Benham warns that on a coarse or sensual hand it intensifies excessive appetites.

Read with care: Popular Indian sources marketing this as a "millionaire's mark" go far beyond anything in the classical texts. The line's protective reading of Life-line breaks is a tradition, not a health prognosis; never present it as a guarantee of longevity.
