Graha Yantra

(1 is on Śanigraha,2 nd Rāhugraha,3 rd Ketugraha
and 4rth janmagraha) floral shaped diagrams on different
planets. At the centre of each diagram is written
Devadatta.Perhaps the diagrams of Maṇḍala Yantra are
prepared by someone Devadatta by name.The first picture of
Sanskrit Śani or Saturn is one of the most influential planet of
Karma . In Sanskrit Śani comes from Śaniścara, which means
slow mover.Instead of rewarding with easy,instant
gratification, Śani’s influence brings obstacles,delays and
hardships.These struggles are designed to teach
patience,discipline, maturity and spiritual growth. In the
diagram Śaniścaragraha śani is written in each of eight petals.
Second one is Rāhugraha. In the eight-petalled floral shaped
diagram Rāhurāja is written in each petals of the diagram.
Rāhu is not a physical planet.It is a shadow entity. Rāhu and
Ketu,the twin planets of Hindu Astronomy symbolize
eclipses.In the next folio (noted as no.14) two floral shaped
diagrams remain,one is on Ketugraha and other is on
janmagraha. In the diagram Ketugraha is written in each of
eight petals and in the diagram Janmagraha janma is written
in each of eight petals.
