STHULA, KANTAKA & KANTAKA STHULA
Sthula: Count the Nakshtras from the Surya to Mula. The Nakshtra arrived at by counting the same from Mula is the unfortunate Sthula “dense/massive” Nakshtra.
Kantaka (कंटक): Dictionary meaning of Kantaka - काँटा, बाधा, विघ्न, दुखदाई वस्तु, हानिकारक वस्तु
Count the Nakshtras from Mangla to Mula. The Nakshtra arrived at by counting the same from Mula is the unfavourable Kantaka “thorn” Nakshtra.
Exception: A planet in its own Varga or in exaltation and aspected by a benefic, is not affected by Kantaka.
Kantaka Sthula: Count the Nakshtras from the Surya to Mula and add to the number of Nakshtras counted from Mangla to Mula. The Nakshtra arrived at by counting the sum from Mula is Kantaka Sthula “massive thorn”, which is very destructive. Remedial forces and even powerful beneficial influences do not diminish its harmful effect.
