Types of Nadi Encrypts – Ancient Tamil Nadi Script, Vattezhuthu & Siddhar Encryption
Learn about the different types of Nadi encrypts used by Tamil Siddhars—Vattezhuthu, Sandhya Bhasha, Jiva Nadi script, poetic encrypts and more. Complete blog on the secret coding system behind Nadi Astrology.
Introduction
Nadi Astrology (Nadi Jothidam) is one of the most extraordinary heritage systems of India, preserved in palm leaves written by ancient Tamil Siddhars thousands of years ago.
What makes Nadi truly mystical is not only the predictions—but the unique encrypted writing pattern used in the palm leaves.
These leaves were NOT written in normal Tamil.
Siddhars used rare forms of encrypted Tamil scripts, secret codes, symbolic letters, and divine poetic patterns to protect the spiritual knowledge.
This blog explains the different types of Nadi encrypts, how they were written, and why the Siddhars coded the information.
Why Were Nadi Leaves Encrypted?
The Nadi leaves contain powerful knowledge such as:
- Destiny of individuals
- Karmic secrets
- Past-life information
- Predictions of kings
- Healing formulas
- Mantras & divine instructions
To prevent misuse and to protect sacred wisdom, Siddhars used encrypted scripts, decoded only by trained Nadi readers.
Types of Nadi Encrypts Used in Palm Leaves (Complete List)
1. Vattezhuthu (Old Tamil Script)
The most common script in Agasthiya Nadi and Kousika Nadi.
✔ Features:
- Rounded letters
- No sharp edges
- Used from 4th to 12th century
- Hard to read without training
✔ Why Siddhars Used It:
Vattezhuthu is simple yet ancient, making it ideal for long-lasting palm-leaf preservation.
⭐ 2. Grantha Script
Used for:
- Sanskrit mantras
- Vedic shlokas
- Astrological formulas
✔ Features:
- More complex than Tamil
- Mostly phonetic Sanskrit sounds
- Seen in Deeksha Kandams & spiritual leaves
⭐ 3. Sandhya Bhasha (Twilight Language)
A secret poetic language used by Siddhars.
✔ Features:
- Symbolic metaphors
- Hidden meanings
- One sentence may have two or three layers
- Used in Siva Nadi messages
Example:
“Aazhi thannil thondrum sudar, un nilaiyai velippadum.”
(Light emerging from the ocean will reveal your state.)
→ Meaning: “Your destiny emerges from deep karma.”
⭐ 4. Mantra-coded Encrypts
Used in:
- Deiva Nadi
- Siva Nadi
- Jiva Nadi
✔ Features:
- Lines start or end with sacred bijaksharas
- Spiritual messages framed as divine dialogue
- Often rhythmic or poetic
⭐ 5. Symbolic Astrology Coding
Siddhars used symbolic representation for:
- Navagraha
- Rasi & Nakshatra
- Doshas
- Planetary remedies
Examples:
- “🔥” symbolizes Mars
- “🌘” symbolizes Saturn
- “🐍” signals Rahu-Ketu karmas
- “🌺” signals marriage blessings
These symbols appear as encoded metaphors in the leaf.
⭐ 6. Jiva Nadi Script (Living Nadi)
The rarest encrypt type.
✔ Features:
- Appears in real time to the reader
- Letters seem to flow like handwriting
- Message is direct, conversational
- Script style differs from Vattezhuthu
Siddhars communicate through psychic mediumship in this form.
⭐ 7. Tamil Chandas (Poetic Metre Encryption)
Many Nadi leaves are written in Siddhar songs:
- Venpa
- Asiriyappa
- Viruttam
- Kappiyam
✔ Why poetry was used:
Poetry compresses meaning, protects sacred knowledge, and creates multi-layered messages.
⭐ 8. Sequential Palm-leaf Numbering Code
Nadi bundles are arranged with:
- Fingerprint pattern codes
- Leaf sequence numbers
- Kandam positioning
- Birth-star categories
This is a classification encryption, not written on the leaf but used for indexing.
⭐ 9. Predictive Riddle Encrypts
Used in advanced Nadi types.
✔ Features:
- Cryptic sentences
- Hidden timings
- Clues for future events
- Must be decoded by experts
Example:
“When the metal bird crosses the southern sky, your path opens.”
→ Metal bird = Airplane
→ Meaning: Opportunity comes during travel.
⭐ 10. Herbal & Medicine Codes (Siddha Nadi)
Medical Nadi texts use:
- Herb symbols
- Number-based formulas
- Coded alchemy terms (Moola, Rasam, Chooranam)
These leaves correlate astrology + medicine.
Why Reading Nadi Encrypts Requires 5–7 Generations of Training
Because:
- Scripts are ancient
- Meanings are layered
- Codes are symbolic
- Interpretation requires intuition
- Knowledge passed orally from Guru to Shishya
This is why some Nadi readers are known for unmatched accuracy across generations.
Conclusion
The types of Nadi encrypts show the brilliance of Tamil Siddhars—how they encoded divine knowledge into protected palm-leaf scripts. These encrypts are deeply spiritual, symbolic, and multi-layered, requiring decades of training to read and decode.
Understanding these scripts gives us a glimpse into the incredible ancient intelligence behind Nadi Astrology, which continues to guide millions even today.
