for Balg followers it’s a little old fashion,
but generally it works:
https://goo.gl/images/x2Fe9C
Focus on the Picture and draw a mental copy of the image into your mind.
Place that Image around you, drawing it in astral lines (white or Purple),
the Triangle should be in front of you, the Circle around you.
Once you’ve drawn the Picture around you,
the Manifestation is already in Progress.
The Runes of that Ritual Set up are well known on the Astrals,
and used for Evokation.
At that point, focus your gaze into the triangle and simply call the Angel you want to work with,
you can go the extra mile and evoke Michael, Uriel, Gabriel and Raphael to stand around you as guiding forces.
(those being the cardinal Arch-Angels:
Uriel, Cardinal Angel of the Northern Corner, Elemental Angel of Earth
Gabriel, Cardinal Angel of the Western Corner, Elemental Angel of Water
Raphael. Cardinal Angel of the Eastern Corner, Elemental Angel of Air
Michael: Cardinal Angel of the Southern Corner, Elemental Angel of Fire
, like the Cardinal Arch-Demons:
- King of the East: Amaymon
- King of the West: Corson
- King of the North: Ziminiar
- King of the South: Gaap
-those are old version, look into E.A.'s works for the current most reliable version.)
However, those are ment to guide you and help you in the process,
a solid Tower Ritual (growing yourself infinately big),
works aswell and furfills the same purpose in therms of power (potential),
but doesn’t come with the concious guidiance those have in store for anyone working with them.
Ah heck, i’ll write it out myself…
1.) Belial
2.) Azazel
3.) Amaymon
4.) Abbadon
-those being the modern version of the cardinal Demons, as in the Grimoire “Book of Azazel.”
Note that any of these can be approached individually and asked for guidiance,
to grant you a familiar which works with you,
etc.
Any of the Deities mentioned here,
are well capable of managing your circumstances and guiding you.
However, each of them is specialized in a specific field,
and you’ll gain the most when not devoting to just one,
but working in aliance with a complete set.
(hence, that’s how Magicians have done it for a very looong time. 
)
Sincerely,
