Transcendental Meditation (TM - repeated states of mind without thoughts of pure contentless
transcendental awareness). Stuart Heritage im GUARDIAN: Where Mindfulness practises overt
observation TM is all about letting go. Measurements of heart rate variability (HRV) showed
that . Transcendental Meditation through Automatic Self Transcending is primarily effective
in producing sustained regeneration and short-term rapid recovery . Mindfulness meditation
on the other hand through sympathetic driven increase in HRV tends to lead to increased
readiness for action and fitness. Recent comparative studies between mindfulness and TM suggest
that TM may yield better results in increasing mindfulness.
