I am attaching a sample of this handbook for those of you who are curious about the differences in the Practical and Advanced Handbooks. I can give you some clue by telling you that the advanced Life Force Handbook will only be useful if you have read Talking to Spirits.
The Advanced Handbook will allow you to create desirable effects on a much wider scale than the Practical Handbook and it will be free as well.
You can download the sample from MEGAsync using this link:
