Gulika or Maṇḍī

Gulika is in puṣyā nakṣatra [Śani⚝ viṁśottarī] in 12th bhāva (Kāraka: Śani) → under advisement of her 7th lord (husband), as a dutiful wife, she put cyanide capsule in the mouth of her sleeping children and then also bit into poison capsule. Saturn afflicts the debilitated hopeless lagneśa Sun by occupying Uttara Āṣāḍha nakṣatra [Su⚝]. The nodes dominate the chart. Although the nīca Sun and Moon conjoin Rāhu trying to break the Sarpa Yoga, they fail as the tithi is amāvasyā ruled by Rāhu. Mercury who could have helped is joining them and is under the influence of this darkness in tulā rāśi. Daśā: Ra-Ju-Me

Should we blame Gulika or Maṇḍī [mn’ in mīna rāśi revatī ⚝Me in 8th bhāva] » what’s the difference?
