Complete surrender with the heart is of utmost importance to achieve bliss. This can be as easy as breathing, if we are connected to our inner self. If not then every darkness and challenge seems like it has come to destroy you permanently. It is the process through which we become wiser and move ahead.
One example which my Reiki teacher, Mr. Surinder Makkar used to give was that if we look at the other or the wrong side of an embroidery piece, we see threads all tangled up, the design unclear and chaos.
