katpayadi Number

There is also a science in the scriptures of Indian spirituality by which you can keep your PIN safe and confidential. The name of that vidya is “Katpayadi Sankhya Vidya” Many of us forget our password, or ATM PIN, due to which we write it down somewhere, but if that piece of paper gets into someone’s hands or is lost, then there is trouble, but our password or PIN No. We can easily remember it by “katpayadi number”

Katapayadi” is an ancient Indian method of easily remembering numbers in the form of words or verses. In India, scientific/technical/astronomical texts were written in verse form, so to express numbers in the form of words, Indian thinkers came up with a solution in the form of ‘katpayadi’. The earliest available evidence of the use of the Katapyadi system is found in the description “Laghubhaskaraya” written by “Sankaranarayana”. The following verse of “Sadratnamala” composed by “Sankaravarman” explains this method
The classical proof of this is presented before you,

नज्ञावचश्च शून्यानि संख्या: कटपयादय:।
मिश्रे तूपान्त्यहल् संख्या न च चिन्त्यो हलस्वर: ॥



Meaning: NA, GHA, and VA represent zero.] The remaining nine digits are represented by consonant letters beginning with AA, TA, IA, and YA. In a combined consonant, only the latter will be taken. Consonants without vowels will be omitted.

discuss what is its usefulness in modern times and how to do it?


Katpayadi number– is a scriptural method of summarizing the number by letters, each number is represented by a few letters such as,

1 – A, T, P, Y
2 – B, B, F, R
3 – C, D, B, L
4 – D, D, B, V
5 – E, N, M, SH
6 – F, R, SH
7 – G, Th, S
8 – H, D, H
9 – I, D
0-J, NA, A, AA, E, E, U, OO, RI, L, A, AI, O, AU


Our Acharyas used them in Sanskrit sentences such as Gauh = 3, SriH = 2, etc.

For this, leave the existing quantity in the middle. The vowel is acceptable if it is at the beginning of the word, otherwise (unacceptable). For example, my ATM PIN is 0278 – but sometimes by remembering the number, we get confused whether it was 0728 or 0278. This also happens often with many people, these are ways to avoid them. Like any four-letter Sanskrit word for ATM PIN, keep that word only in your mind, do not tell anyone

For example–

Ibhastutyah = 0461

GanapatiH = 3516

Gajeshan = 3850

Narasimha = 0278

Janardanaḥ = 8080

Sudhyupasyaḥ = 7111

Shakuntala = 5163

Sitaram: = 7625

Choose any word from your own :
Remember any such word and immediately change the “katpayadi Number” to use your ATM PIN etc.
