Blessing & Peace be with you all.
So this is the main question that`s be making me feel like i`m going around in circles and makes me want to due to different answers.
Is there any scripture that says:
1.)God & Goddess & deva are all the same i.e goddess and deva are just God but in different form and not seperate entities/spirits?
2.)Shiva,ganesh,visnu etc are all one god but diffent aspect?

Some say or make it sound like that god is one but shiva,ganesh and the other gods/deities just help god with different jobs i guess like a job the manager owns the business but he/she has staff that helps him/her,and others say no it`s all one.

Thank you for any help.
