Lo Shu Grid Arrows and Planes: A Complete Guide

The eight lines of the Lo Shu square turn a list of numbers into a story. Each row, column and diagonal links three numbers into one theme. This guide explains every line, how to judge it complete, empty or partial, and how to read two contrasting charts.

The square and its eight lines

The Lo Shu is a 3×3 magic square. Every line of three adds to 15, and each digit has a fixed home:

4 | 9 | 2
---------
3 | 5 | 7
---------
8 | 1 | 6

There are exactly eight lines: three rows, three columns and two diagonals. If a source describes a "line" that is not one of these, it belongs to a different grid system.

This library plots every non-zero digit of the full date of birth (DD MM YYYY). Zeros are not plotted, and repeats are shown by repetition ("99"). For a refresher on building the grid, see the Lo Shu grid practitioner's guide.

Naming varies by school

Names for the planes differ between teachers, books and traditions. Some call the top row the "mind plane", others the "thought plane". Some Indian schools call the 2-5-8 diagonal the Raj Yog arrow. Some practitioners call 4-5-6 the "golden" line and 2-5-8 the "silver" line.

None of these names is wrong. The risk lies in mixing them. Choose one convention, write it into your notes and use it with every client. This library uses the names below.

The three rows (planes)

The rows describe where a person's energy naturally sits: in thought, in feeling or in practical action.

The three columns

The columns describe how energy moves from idea to result. Many practitioners read them as a sequence: plan (4-3-8), commit (9-5-1), act (2-7-6). A gap shows where the sequence tends to stall.

The two diagonals

Both diagonals, the middle row and the middle column pass through 5. A missing 5 leaves four lines unable to complete.

Complete, empty and partial lines

Every line falls into one of three states.

• Complete (arrow of strength): all three boxes hold at least one digit. Repeats do not matter here; "99" counts as one filled box.
• Empty (arrow of weakness or missing arrow): all three boxes are blank.
• Partial: one or two boxes are filled. Most lines in most charts are partial.

Partial lines are not usually named as arrows, but they still carry information. A line with two of three boxes filled is often read as a capacity close to complete.

Reading the strength of a complete line

A line of single digits is generally read as balanced. A line with one heavily repeated box, such as 9-5-1 with "999", may lean towards that number's traits. Repeats are a separate layer, covered in zeros and repeats in the Lo Shu grid and in over-energy in numerology.

Language with clients

"Arrow of weakness" is a technical term, not a verdict. Frame empty lines as areas that ask for conscious effort or structure. "This is an area where routines will help you" lands better than "you have a missing action arrow".

Worked example 1: a chart full of arrows

Our first fictional client was born on 24 June 1985.

Step 1: list the digits

24 06 1985 → 2, 4, 0, 6, 1, 9, 8, 5. Remove the zero.

Missing numbers: 3 and 7.

Step 2: draw the grid

4 | 9 | 2
---------
- | 5 | -
---------
8 | 1 | 6

Step 3: check all eight lines

Five lines are complete; none is empty.

Step 4: interpret

The mental and practical planes are complete, as are the will column and both diagonals. Within Lo Shu practice, this suggests a client who thinks clearly and delivers practically, with steady achievement and care for others.

The only gaps, 3 and 7, both sit on the emotional row, which holds only 5. You might explore whether this client is more comfortable with plans and results than with expressing feelings.

Variation check: the driver is 24 → 6. The component Life Path is 6 + 6 + 5 = 17 → 8, and the full-digit method also gives 35 → 8. Adding a 6 and an 8 fills neither 3 nor 7, so the lines do not change.

Worked example 2: a chart with missing arrows

Our second fictional client was born on 3 July 1977.

Step 1: list the digits

03 07 1977 → 0, 3, 0, 7, 1, 9, 7, 7. Remove the zeros.

Missing numbers: 2, 4, 5, 6 and 8.

Step 2: draw the grid

- |  9  |  -
-----------
3 |  -  | 777
-----------
- |  1  |  -

Step 3: check all eight lines

No line is complete; both diagonals are empty.

Step 4: interpret

The empty diagonals follow from the missing 5 and the missing corners 4, 6, 2 and 8. The 9-5-1 will column has 9 and 1 but lacks its centre.

The triple 7 is the most striking feature. A heavy 7 is traditionally associated with introspection and a pull towards solitude, and some practitioners read it as over-energy. A useful conversation might explore how this client turns reflection into steady progress.

Variation check: the component Life Path is 3 + 7 + 6 = 16 → 7 (year 1977 → 24 → 6), flagging karmic debt 16/7. Adding the driver (3) and conductor (7) gives "33" and "7777", but the diagonals stay empty.

How to use lines in a reading

1. Mark each of the eight lines as complete, empty or partial.
2. Start with complete lines, the client's natural strengths.
3. Move to empty lines, framed as development areas.
4. Note partial lines one digit short; these are often the easiest themes to work on.
5. Only then add repeats, missing-number meanings and any remedies.

Record which naming convention and plotting rule you used, so your notes still make sense next year.

Key points

• The Lo Shu has exactly eight lines: three rows, three columns and two diagonals.
• A complete line is an arrow of strength; a fully empty line is a missing arrow; most lines are partial.
• 5 sits on four lines, so its presence or absence shapes the whole grid.
• Plane names vary by school (Raj Yog, golden, silver). Pick one set and use it consistently.
• Always state whether you added the driver and conductor, as this can change which lines complete.

Frequently asked questions

Does a repeated digit make a line "stronger"?

Not for deciding completeness. A box is either filled or empty. Repeats add emphasis to that number's traits, read as a separate layer.

Is 2-5-8 always called the Raj Yog arrow?

No. That name is common in some Indian schools, while others call it the compassion, spiritual or silver line. Use whichever term you were trained in and keep it the same across clients.

Should I read partial lines at all?

Yes, briefly. A line one digit short often points to the most achievable growth area.

If you calculate many charts a week, software such as the NumberTeller Lo Shu grid tool can apply these rules the same way for every client — but know the method yourself, so you can check any result.
