Why my mind brood of past or become anxious of future, instead of living in present?
Everyone’s mind does that so you are very normal. Even mine.I get frustrated and tired of all the crap too.But it is not possible to be happy all the time.Have you ever seen a smile on Buddhas or Jesus’ face?Even when Krishna died He saw his own sons and grandsons kill each other in front of Him.Ramkrishnaji died of cancer,Saibaba died with sorrow in heart.Even your ideal Vivekananda sat thinking of the future and the past with his master with sadness on the rock!They too never had peace but it is not about having peace but living life the way you can be happy!That means if you like vadapao or misalpao in the rains, go and get it and be in the present.
