How does Lord Shiv teach us to be a Yogi?

In this Shravan month Sandesh by Pujya Bhaishri, through an infographic, the symbolisms of the form of Lord Shankar are explained, such as Gangaji on His head, the moon on His head, the snake on His neck, the ashes on his body and his blue throat. Pujya Bhaishri also expounds on how these symbolisms therefore make Lord Shiv a Yogi and Mahadev (the master of demi-gods).
