What is the meaning of cross above bracelet lines?
As you know in palmistry cross sign is considered very inauspicious sign but at some places on hand cross sign is considered auspicious.
For example (1) cross on Jupiter Mount gives good results to subject (as per palmistry books cross on mount of Jupiter denotes good marriage, love marriage, subject is loyal, marry to rich person, etc but in my practical this is not always true).
Cross on Mount of Ketu also indicates skin diseases. See above image, cross above bracelet is marked by red circle.
Usually cross on palm indicates accidents, suicide, operation, health problems, financial loss, deception and defamation, etc but on Mount Jupiter and Ketu gives good results to subject.
Mystic cross is totally different sign than cross sign on lines and mounts.
