【正文】 。如果我們一味逃避生活中的悲傷，悲傷只會(huì)變得更強(qiáng)烈更真實(shí) ——悲傷原本只是稍縱即逝的情緒，我們卻固執(zhí)地耿耿于懷 By utilizing our breath we soften our experiences. If we dam them up, our lives will stagnate, but when we keep them flowing, we allow more newness and greater experiences to 吸能減緩我們的感受。下面六個(gè)方法有助于你更完滿(mǎn)透徹地敞開(kāi)心扉。我們假裝一切仿佛都不曾發(fā)生，以此試圖忘卻傷痛，可就算隱藏得再好，最終 也還是騙不了自己。t remember his appearance.

Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere ) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere.
