It may seem abstract to provide guidance, but I Suggest that you light candles for your spirits. Spirits LOVE such attention! :)
When you meditate, you should FOCUS on your Goal. And the goal is to attract the right guide for you. Be open and show some love. Be specific with what kind of help you want of the spirit.
Meditate a few times a week.
Finding the right guide is like finding the perfect partner.
A guide is a spirit of great experience. It may take time before you find a good guide.
Some may have multiple guides. It leads to chaos when everyone is trying to help at the same time. ;)
However, you should not belive in Everything a guide says. Thay can also be wrong. But the intention is good, and with time you will develop a nice relationship.
