The Lo Shu Grid
A 3×3 grid, nine numbers, and a date of birth — the Lo Shu system is one of the oldest number maps of a human being. Present numbers reveal where energy flows freely. Missing numbers reveal where the chart needs deliberate work. This is the full reader's guide.
The base grid
The Lo Shu grid always has the same nine numbers in the same nine positions. Every row, column, and diagonal sums to 15 — that is the mathematical signature that makes it a magic square, and the reason it has anchored Chinese, Indian, and Vedic numerology for more than two thousand years.
| 4 | 9 | 2 |
| 3 | 5 | 7 |
| 8 | 1 | 6 |
Rows, columns, and main diagonals all add to 15.
How to read your own grid
Write your full date of birth — day, month, year — and strike out every zero. Count how many times each digit from 1 to 9 appears. Place each count at that number's fixed position in the grid. The pattern of present, missing, and repeated numbers is your reading.
Example — 15 August 1982: The digits, with zeros removed, are 1, 5, 8, 1, 9, 8, 2. So the grid shows 1 twice, 2 once, 5 once, 8 twice, 9 once — and 3, 4, 6, 7 are missing. Five of the nine numbers present is a moderately filled grid; the missing cluster (3, 4, 6, 7) will be the reading's centre of gravity.

The nine numbers and their planets
Each number in the grid is ruled by a planet in Vedic astrology. When the number is present, the planet's energy is available to you; when it is missing, that planet's domain is the area of life that needs deliberate attention.
- Number 1 — Sun — Identity & self-expression. The number of who you are in public — confidence, leadership, visibility.
- Number 2 — Moon — Sensitivity & intuition. The number of emotional intelligence — how deeply you feel and how well you read others.
- Number 3 — Jupiter — Wisdom & creative expression. The number of the teacher and the creator — imagination, writing, teaching, growth.
- Number 4 — Rahu — Discipline & unconventional thinking. The number of structure under pressure — routines, systems, and original angles.
- Number 5 — Mercury — Balance & communication. The centre of the grid — versatility, commerce, and the bridge between mind, heart, and body.
- Number 6 — Venus — Love, family, aesthetics. The number of warmth — relationships, home, beauty, artistic sensibility.
- Number 7 — Ketu — Spirituality & detachment. The number of the seeker — research, introspection, and the pull beyond the material.
- Number 8 — Saturn — Discipline, structure, karma. The number of compounding — patience, long-horizon work, and financial architecture.
- Number 9 — Mars — Courage, energy, action. The number of drive — physical vitality, decisiveness, and willingness to fight for what matters.
The six planes
A plane is a complete row or column of the grid. Each plane groups three numbers whose shared meaning describes a dimension of the personality. Three horizontal planes describe what is happening — mind, emotion, practical life — and three vertical planes describe how you move through it: thought, will, action.
- Mind Plane (4 + 9 + 2) — Top row — intellect, memory, planning
- Emotional Plane (3 + 5 + 7) — Middle row — feeling, intuition, inner life
- Practical Plane (8 + 1 + 6) — Bottom row — money, action, material life
- Thought Plane (4 + 3 + 8) — Left column — generating and processing thought
- Will Plane (9 + 5 + 1) — Centre column — willpower, direction, inner fire
- Action Plane (2 + 7 + 6) — Right column — execution, completion, results
Arrows of strength
An arrow forms when every number in a plane — or a key diagonal — is present in your birth date. Arrows are not subtle signatures; they are defining traits that shape how other people experience you.
- Arrow of Determination (1 + 5 + 9) — 1 + 5 + 9 all present — resilience and inner fire
- Arrow of Intellect (3 + 5 + 7) — 3 + 5 + 7 all present — sharp analytical mind
- Arrow of Prosperity (2 + 5 + 8) — 2 + 5 + 8 all present — natural money magnetism
- Arrow of Stability (4 + 5 + 6) — 4 + 5 + 6 all present — grounded and adaptable
- Arrow of the Planner (4 + 9 + 2) — 4 + 9 + 2 all present — strategic and logical
- Arrow of Spirituality (3 + 5 + 7) — 3 + 5 + 7 all present — intuitive and kind
- Arrow of Action (2 + 7 + 6) — 2 + 7 + 6 all present — finisher energy
- Arrow of Willpower (9 + 5 + 1) — 9 + 5 + 1 all present — iron will
Arrows of weakness
A weakness arrow forms when an entire row or column is empty. Unlike missing numbers in isolation, a weakness arrow indicates a structural gap — a whole dimension of experience needs attention. The remedies are behavioural first, ritual second; reading the description closely is the first step.
- Arrow of Frustration (4, 5, 6 all missing) — 4, 5, 6 all missing — repressed energy, emotional churn
- Arrow of Poor Memory (3, 5, 7 all missing) — 3, 5, 7 all missing — scattered recall
- Arrow of Loneliness (2, 7, 6 all missing) — 2, 7, 6 all missing — goal-focused, relationship-thin
- Arrow of Losses (8, 1, 6 all missing) — 8, 1, 6 all missing — money and effort leakage
- Arrow of Indecision (4, 3, 8 all missing) — 4, 3, 8 all missing — overthinking
- Arrow of Passivity (9, 5, 1 all missing) — 9, 5, 1 all missing — waiting for others
Missing numbers are not curses
Every date of birth has missing numbers — that is the nature of a nine-cell grid and a ten-digit calendar. A missing number is a pointer, not a verdict. It is telling you which planetary energy needs deliberate cultivation rather than assumed access.
The traditional remedies — a gemstone, a mantra, a colour — are the visible surface. What actually moves the needle is the underlying behaviour the remedy points to. A missing 1 asks you to practice visibility. A missing 4 asks you to install routines. A missing 6 asks you to put people before projects. Read each number's page for the behavioural prescription.
Lo Shu and Chaldean numerology
Lo Shu reads the pattern of your date of birth — which numbers show up, which are missing, which arrows form. Chaldean numerology reads the totals — your life path number, destiny number, personal year. The two systems are complementary, and a full reading uses both: Lo Shu for the shape of your inner wiring, Chaldean for the headline themes of your life.
Common questions
- What is the Lo Shu grid?
- A 3×3 magic square of the numbers 1–9 in which every row, column, and diagonal sums to 15. In Indian and Vedic numerology it is used to read personality, strengths, and missing planetary energies from a date of birth.
- How do I build my Lo Shu grid?
- Write out your full date of birth (DD-MM-YYYY), ignore every zero, and count how often each digit 1–9 appears. Place each count at that digit's fixed position in the grid. Present numbers reveal strengths; missing numbers reveal areas to cultivate.
- What does a missing number in the Lo Shu grid mean?
- A missing number indicates that the ruling planet's energy is not automatic in your life and needs deliberate cultivation. It is a pointer, not a curse — the per-number pages lay out the behavioural and remedial work that traditionally strengthens each missing channel.
- What is an arrow in the Lo Shu grid?
- An arrow is a complete plane — three numbers that together form a full row, column, or key diagonal. Present arrows (strengths) describe defining traits; weakness arrows (entirely missing rows or columns) describe structural gaps that shape daily experience.
- How is Lo Shu different from Chaldean numerology?
- Lo Shu reads the pattern of digits in your date of birth — which numbers show up, which are missing, which arrows form. Chaldean numerology reads the totals — destiny number, birth number, personal year. The two systems are complementary; a full reading uses both.
