There are three major lines on your palm. These include the
- heart line
- head line
- life line
Basically, the major hand lines represent
- emotional energy (heart line)
- mental energy (head line)
- physical energy (life line)
In simple terms, body, mind and soul. They are found on every hand, even if the heart line and head line are sometimes merged into one line, called the simian line.
Kathleen E. Keogh, Vedic Palmist-Astrologer, gives wonderful insights on the major hand lines in this video.
