Benefic Grahas gathers the two of the nine grahas of Jyotisha classified simply as benefic, without the mutable or waxing qualifier attached to two of their fellow grahas: Guru and Shukra, the gurus respectively of the gods and of the demons.
Guru, Jupiter, is devaguru, guru of the gods, and karaka of wisdom, dharma, higher knowledge, children, wealth and grace, signifying teachers, priests, law, the liver and fat; he expands and blesses whatever he touches. Exalted in Karka, debilitated in Makara, and ruling Dhanu and Meena, his day is Thursday, his gemstone the yellow sapphire, his metal gold, and his Vimshottari period sixteen years. A strong Guru is said to give faith, generosity and good fortune; afflicted, it brings dogmatism, excess or trouble with children and gurus.
Shukra, Venus, is daityaguru, guru of the demons, and shares the unqualified benefic classification with Guru alone among the nine; he is karaka of love, beauty, pleasure, art, marriage and refinement, signifying the spouse, vehicles, luxury, reproduction and the eyes, and teaches the enjoyment of the world and the arts of harmony. Exalted in Meena, debilitated in Kanya, and ruling Vrishabha and Tula, his day is Friday, his gemstone the diamond, and his Vimshottari period twenty years, the longest of all nine. A strong Shukra is said to give charm, artistic gifts and happy relationships; afflicted, it brings indulgence or marital discord.
Both belong to the nine grahas, the seizers, set out in the Brihat Parashara Hora Shastra and attested earlier still in the Yavanajataka of Sphujidhvaja, the Sanskrit rendering of a lost Greek horoscopic manual; the atlas records that lineage on both figures rather than treating the classical Indian source as the whole of their history.
