During my Personal weight training of session in Gym, I was doing my squats, and my thigh muscles were literally paining and burning, I closed my eyes to hold and bear my pain. I heard my trainer say "Breathe". I tried to breathe, initially when I tried, it was hard for me to breathe, my mind was only focussed on the pain in my muscles and i was unable to relax. But slowly i started to breathe, and in the subsequent sessions I realized it really helps.
This whole week, every morning as I commute to work from NJ to NY, everytime I think of the issues and challenges that have to face at work that day. I just hear only one word, "Breathe". And as I start breathing, I realized that the fear and thoughts, which were blocking my mind immediatly fades away. And I remember the verse in Genesis 2:7 "then the LORD God formed the man of dust from the ground and breathed into his nostrils the breath of life, and the man became a living creature" (NIV) The love of God fils my heart and the stress fades away.
I love the fact that God promised to "give you a heart of flesh, " Ezekiel 36:26 (NIV) to the people whom he loves. When His spirit comes in and makes a dwelling, we get a tender heart. But the challenge is the stress around\ us makes us hard hearted, like how pharaoh hardened his heart, when Moses came to Him and asked to let the Isrealites go out of Egypt.
Everytime stress comes in we harden our heart and stop breathing, which leads to lack of Spirit, joy, hope, faith inside us. But by learning to hold on to the breath under stress, really helps us to be Joyful and happy.
