I'd like first to warn you that I'm french, so you don't expect perfect english :-)
I hope I remain understandable in my posts.
It's been a long time since I've first subscribed and written on this forum. I'm glad to be back.
I've recently witnessed some imbalances in my practice, and I'd like to witness about it. First a brief flashback on my practice: I discovered AYP website at the beginning of 2011. I constructed my practice on 2 daily sessions of pranayama and DM. Everything went fine except strong pains in the chest that I managed through self pacing.
I talk about my practice to a friend of mine who's teaching yoga, and she talk to me about kriya yoga. I took the initiation on June of 2011 followed by a 4 days retreat, at the end of which I've been accompanied with a rather strong pressure in the forehead that has never gone off since then.
My kriya yoga practice has oscillated between total dedication (1 hour session pr/dy for months) and total abandonment (no practice for weeks or months).
Lately I have practiced each and every day for 4 months, before my first children is born and from then I couldn't manage to find the time and the necessary rest to practice seriously.
2 or 3 months after stopping practice (I've not been practicing for almost 5 months), some unpleasant side-effects appeared : the pressure in the forehead, which has already been there, became very strong and uncomfortable. At times it was like a extremly concentrated point was pulsating in my forehead. When it hits that hard, I became irritated, angry and emotionally unbalanced.
Also, I experimented some strong dizziness, with the sensation of flush of dizzy energy in my head. I had them everytime I would sit or stand up or bend, especially in the evening with the fatigue of the day.
Weeks after weeks, it became unbearable so I decided to start practice again. I have no direct contact with a kriya yoga master so it's difficult to get advices and clear instructions except than "continue meditation" and "I will pray for you" (don't get me wrong here: I'm not angry at anyone, but I was expecting a bit more).
So I'm back to AYP which provided me a lot more pleasure and comfort in a few months than kriya yoga ever did. I'm not really in the position to compare both of them though, as they truly unveil their potency after months or years of practice. Dont' take my post as the expression of the Universal Truth; just a subjective point of view on the subject.
I'm also more confident in AYP because SBP and DM has lowen these unpleasant side effects to such degrees that I barely noticed them now. I'm doing a daily practice of two sessions pr/dy (10 min SPB + 20 min DM) that suits me very well, and is easier to integrate to daily life than kriya yoga practices.
So I'm here, following the AYP path now, and I'll let you know how it goes :-)
