I have learnt that in the Navagrahas there are friends and enimies like say saturn and surya are enimies. some other go well together. when i was wearing a blue sapphire on my ring finger it was advised to me that ring finger belongs to surya so blue sapphire which is for saturn if is on the ring finger will bring adverse affects. Is this true. And if so can we perform japa of a graha say saturn on its enimies day i.e surya. In the panchang in a day each hour is governed by one planet so when can we perform japa.
