The advice is to establish a solid basis in meditation before you undertake any kundalini stimulating practices. When you’ve developed some inner silence as a result of meditation, it will then safe to slowly build up some energy cultivation practices. All the details are given in the AYP lessons. The recommendation is to start reading them from the beginning: http://www.aypsite.org/10.html
