Lo Shu Grid Calculator
Enter your date of birth to build your Lo Shu grid. You will see which numbers are present, which are missing, which arrows of strength and weakness are forming, and which planetary energies need attention.
How the calculation works
Every digit in your date of birth is placed on a fixed 3×3 grid. Zeros are discarded because zero has no planetary ruler in the system. The remaining digits are counted: a digit present once or more activates its cell, a digit absent leaves its cell empty. From the pattern of present and missing digits, the system reads planes (rows and columns), arrows (diagonals and full lines), and repeated-count effects.
Why this grid anchors Indian numerology
The Lo Shu square is the oldest known magic square — every row, column, and diagonal sums to 15. In the Vedic yantra tradition it is the base from which every planetary yantra is derived: a Sun yantra is the Lo Shu grid with zero added to every cell, a Moon yantra with one added to every cell, and so on. This is why Lo Shu reading and planetary remediation are the same practice in AstroMedha's system.
