Katapayadi :
A lesser known and rarely used system for finding out the rashi based on the complete name. I am hereby attaching the table and explaining the usage with the help of an example.

Example Saurabh - write the name in Hindi. Ignore the matras and take only Varna. For Saurabh , it's sa + ra + bha . The corresponding number in the table is 7 for sa, 2 for ra and 4 for bha . That makes it 724 . Now reverse it to 427 .

Divide 427 by 12 and find out the remainder . It's 7 in this case. So the name Saurabh is tula rashi. This is another way of deciding the impact of sade sati and various transits . Few people use naam rashi along with chandra rashi. This technique is rare but very effective.

We can take it one step further and map it back to natal chart to gauge the impact. As per traditional astrologers this is how the impact of name is said to be prime importance .
Ps : this is just one of the usage of katapayadi .
