Ch. I – Miśrakādhyāyaḥ 5 6. If Nandā is in Śukra, Bhadrā in Budha, Jayā in Bhauma (Mars, Maṅgala), Riktā in Śani and Pūrṇā in Guru (Bṛhaspati) then the lunar days bring success in all spheres. 7. If Ekādaśī, falls in Guru (Jupiter) Ṣaṣṭhī in Bhauma (Mars), Trayodaśī in Śukra, Aṣṭamī in Arka (Sun) Eka (Pratipada) in Nandā, Navamī, Daśamī, Dvitīyā in Candra (Moon) - these bring success. 8. There will be fulfillment of desire if Riktā yoga falls in Ravi (Sun) and Śani (Saturn) and Bhadrā fall in Candra and Budha (Mercury). King Soma has said this in the book named Mānasollāsa. 9. If Saptamī falls in the Sun then there will be Muśala Yoga, and Saṁvarta Yoga will occur if Pratipada falls in Mercury. If Karka (Cancer) falls in the 13th position then the three solar and lunar days are to be discarded. 10. Maghā, Viśākhā, Ārdrā, Mūlā, Rohiṇī produce Yamaghaṇṭa yoga on an inauspicious Sunday and other days. 11. If the four stars Viśākhā etc fall serially in the Sun and others then there will be Utpāta, Mṛtyu, Kāṇa, Siddhiyoga² and the last one is auspicious. 12. If Hastā, Mṛga, Aśvinī, Maitra, Puṣyā, Pauṣṇa, and Rohiṇī stars enter into the Sun, the result will be Amṛta and Siddha, it brings success in all spheres. 2. Siddhiyoga- If Nandā falls on Friday, Bhadrā on Wednesday, Pūrṇā on Thursday, Riktā on Saturday and Jayā on Tuesday — then it is known as Siddhiyoga.
