Okay soo 
i am a walking example of BE CAREFUL What you ask for, Similar to how Asbjorn worked with odin. From shiva I asked for guidance and wisom, from Ganesh i asked for help learning how to remove obsticales myself both internal and external. From Durga I asked for to learn ways to pruify myself and my life.
The 2-3 years i worked with these gods was possibly some of the most chaotic times in my life. After which i came through the other end with everything i asked for and a much prosperous life before i started.
If you notice most of my requests are to learn how they do what they can do. And as a result things were manifested in my life that required me to learn how to do these things. Which as a result comes with the need for chaos, obstacles, corruption ect. In order to learn how to do a thing there must be a need to do it And im sure shiva isnt done with teaching me by a long shot. More than 5 years later i will still have moments where synchronicities and symbols tied to him will spring up in my current work. Which isnt surprising since it involves the more primordial aspects of these gods.
