But do you know the amount of tension the heart is put under whilst doing simran? I have seen the style alot of the sangat does simran (esspecially at AKJ events), where the tendancy is to say the true name 'Waheguru' whilst one is breathing out and in.

Try saying anything whlist breathing in and see how difficult it youself. When you breath in the intra-thoracic pressure increases above the set point therfore the venous blood return to the heart decreases and hence the blood pressure falls. To counteract this physiological change the the stroke volume and the heart rate increases which increases the cardiac ouput. Together with slight vasoconstiction and and an elevated cardiac output, the blood pressure is restored.

My point is the heart is naturally put under stress whilst breathing in and the fact that actualy saying something whilst breathing in puts ones heart under more stess. You may think the risks are not reall but you very occasionally see many singers and ragi's with heart desease.
