Strange throbbing

["Maximiliano Markous" <mmarkous@...>]

As I get more relaxed during the mental exercises ( specially if I´m lying down 
) I start to perceive the rythm of my respiration and ( later ) of my heart 
more clearly. If I gert more relaxed I begin to experience a thirdbeat. It´s 
like a throb but it doesn´t come from my heart...it´s like some pulsating 
energy mainly focused on my chest and abdomen. I don´t perceive all the time 
because I think is motre subtle than my respiration orheartbeat.
Has anybody experience this and know what it is? or I´m alucinating??
