Bhagwan Shiv Ji - The God Of Yoga
Bhagvan Shiv ji besides being the god to whom other gods pray to is also seen as the first yogi or ādiyogi and the first guru or ādiguru. Many thousand years ago, on the banks of lake Kantisarovar in the Himalayas, ādiyogi poured his profound knowledge into the legendary saptrishis also known as cosmic saptarishis or "seven sages". These sages carried this powerful message of Yoga to different parts of the world including Asia, the Middle East, Africa and North and South America.
As time passed by, many yugas came and passed by, knowledge diluted and in some cases was lost. Evenually Bhagvan Krishna came and gave a perfected translation in his sermon to arjun which was narrated by Sanjay to Bhagvan Ved Vyas and passed to us in the form of the holy Shrimad Bhagvad Gita which explains every deep aspect of oga holistically, therefore Bhagvan Krishna came to be known as Yogeshwar.
"शिवस्य हृदयम विष्णुर्विष्णोश्चा हृदयम सिवाह"
English Translation -> "Sivasya hridayam vishnur-vishnoscha hridayam sivah"
Meaning -> "Vishnu is the heart of Siva and likewise Siva is the heart of Vishnu".
ॐ नमः शिवाय
ॐ विष्णवे नमः
ॐ नमः भगवते वासुदेवाय
