I know that Shiva, Durga, Vishnu, Surya and Ganesha are counted as manifestations of Nirguna brahman. Or in other way when nirguna brahman is seen through lens of maya, it is seen in 5 different ways. What I fail to make sense of is how come Vishnu is there in the list, but his wife is missing. Similarly, how same saguna brahman Shiva, Durga, Ganesha are related as husband , wife, son and then instead of another son Karthikeya we have Surya as fifth. I am also not able to make sense of the number 5 and one family having 3 saguna brahman. The thing is since all are manifestations of Nirguna brahman, there should be no hierarchy between each of them.
I am not interested in Adi Shankaracharya's views because I already asked a similar question before. There may be different advaitic sects each with their own variations. This question is for those who believe nirguna brahman & saguna brahman seen in 5 ways depending on the person's nature.
Can some explain logically how it is possible?
