The explanation of the horoscope given by Bhaktivinoda Thākura is that at the time of the birth of Lord Caitanya Mahāprabhu the constellations were situated as follows: Śukra (Venus) and the constellation of the Aśvinī stars were in the Meṣa-rāśi (Aries); Ketu (the ninth planet) and Uttaraphalgunī were in the Simha-rāśi (Leo); Candra (the moon) was in Pūrvaphalgunī (the eleventh lunar mansion); Śani (Saturn) and Jyeṣṭhā were in Vṛścika (Scorpio); Bṛhaspati (Jupiter) and Pūrvāṣāḍhā were in Dhanu (Sagittarius); Maṅgala (Mars) and Śravaṇā were in Makara (Capricorn); Ravi (the sun) was in Kumbha-rāśi (Aquarius); Rāhu was in Pūrvabhādrapāda; and Budha (Mercury) and Uttarabhādrapāda were in Mīna (Pisces).

TRANSLATION
According to the Jyotir Veda, or Vedic astronomy, when the figure of the lion appears both in the zodiac and the time of birth [lagna], this indicates a very high conjunction of planets, an area under the influence of ṣaḍ-varga and aṣṭa-varga, which are all-auspicious moments.
PURPORT
The divisions of the  ṣaḍ-varga  area are technically called  kṣetra ,  horā ,  drekkāṇa ,  navāṁśa ,  dvādaśāṁśa  and  triṁśāṁśa . According to Jyotir-vedic astrology, when it is calculated who rules the constellation of six areas, the auspicious moment is calculated. Śrīla Bhaktisiddhānta Sarasvatī Thākura, who was previously also a great astrologer, says that in the book named  Bṛhaj-jātaka  and other books there are directions for knowing the movements of the stars and planets. One who knows the process of drawing a straight line and thus understands the area of  aṣṭa-varga  can explain the auspicious constellations. This science is known especially by persons who are called  horā-śāstra-vit , or those who know the scripture of the name  Horā . On the strength of astrological calculations from the  Horā  scripture, Nīlāmbara Cakravartī, the grandfather of Śrī Caitanya Mahāprabhu, ascertained the auspicious moment in which the Lord would appear.
