What about Angels?

Angels have always been a topic of doubt, of mystery. Throughout the generation people always wanted to interact with them, they have tried to understand them or tried to prove their existence. Judaism has it’s own tradition on how to relate to Angels and even to define an Angel. There is an episode where Angels visit Abraham Avinu in parashat Vayera, from what is written, it can be assumed that they (the Angels) came in human form. Other times Angels are referred as spiritual beings that go beyond our understanding. 

Jewish tradition holds that there are almost infinite number of Angels in all of the levels of creation. There are many different types of Angels from the Angels humans are capable to create through the speech till the Angels Hashem Himself made that are in the highest of the levels. Depending on the type of Angel, they would need to take a physical garment (aka human body) to fulfill their mission or to stay in their spiritual state of being. When an Angel actually shows as a human, they have to behave under the human rules.

Interaction with Angels is not necessary only for the holy people, as it can be seen in parashat Vayera, the Angels were interacting with the people of Sedom, even though the people from Sedom were not very righteous. So it means the interaction can occur with any human being...
