How meditation controls stress? 

Evolution gifted us many qualities, among them the most significant one is known as stress. During stress our heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and our senses become sharper and many body functions like digestion and etc. stops. These physical changes increase our strength & stamina, fast our reaction time, and enhance our focus to either fight or flee from the danger at hand.

Stress is primarily a physical response. when we feel stressed, internally some changes take place. The body thinks it is under attack and switches to ‘fight or flight or freeze’ mode. Sometimes it is internal. When we have unnecessary thoughts,  imagination, anger, anxiety, illness, diatery problems and etc. Our body releasing  a complex mix of hormones and chemicals such as adrenaline, cortisol and norepinephrine to prepare the body for physical actions. This stress hormones in the long run develop heart disease, diabetes and etc.

Earlier we got no ideas, about how brain functions during meditation. Recent study with the help of new technological instruments researchers  made functional MRI scans in short fMRI on a meditating person and,  found amazing results. 

It has been observed that our brains stop processing information as actively as they normally would. 
In Stress reliving meditation,  we are focusing to a single object, or vibration and this eliminates other thoughts and information gathered in our brains,  make us stress free. 

In ‘Joy Tantra Meditation’, exercise is carried on a focus point, which actually blocks incoming thoughts and inward information. This makes the meditation technique an unique mechanism to kill stress instantly.
