  The heart beat data recorded from samples before and during meditation are
analyzed using two different scaling analysis methods. These analyses revealed
that mediation severely affects the long range correlation of heart beat of a
normal heart. Moreover, it is found that meditation induces periodic behavior
in the heart beat. The complexity of the heart rate variability is quantified
using multiscale entropy analysis and recurrence analysis. The complexity of
the heart beat during mediation is found to be more.
