samadhi

Adiguru shankaracharya,together with his linga sharira (the subtle body vis a vis the five faculties of knowledge,the five faculties of action,the five pranaas,the mind and the intellect),raised his prana-shakti and linga sharira,he laft his gross body of through the brahmrandhra and entered the body  of the through his (king's) brahmrandhra making him animate gradually up till his toe

As,in this type of samadhi,the atma-tattva,the prana-shakti as well as the linga sharira leave the gross body completely;therefore,it is quite natural for all the biological processes in the body to come to a standstill.That's why when this state is gauged through the scientific instruments ,all readings come out to be nothing but nil.The pulse rate appears to be zero,the respiration rate is nill the pulse rate appears to be zero,the respiration rate is null,and the ECG and the EEG project a straight line.As a result,in such a condition,the body of the self -Released soul or a yogi who is in Samadhi appears to be lifeless/clinically dead.But a remarkable fact to be hoighlighted here is that when such elevated souls return from Samadhi,their terminated biological processes re again normalcy 

The above -mentioned references clearly assert that in the state of deep Samadhi,the  body of self-Reliased soul/yogi appears to be lifeless/clinically dead.thus,being oblivious to the estoteric realm of spirituality,the contempory scientific world declares the body of the self-Realised soul/yogi in samadhi as a dead body and his state of samadhi as of death.on the same lines,the doctors have designed His Holiness Ashutosh Maharaj Ji's divine state of samadhi as clinical death'.
