there is no growth and development in our life unless we unlearn and learn new things...whether positive or negative...redundant knowledge is always no use....

yes...when we remain satisfied with the acquired knowledge and wisdom we remain where we are...stagnant...in wealth, fame, contentment and become a walking coffin after some time!...we never grow further, mature, develop etc....when we unlearn then we feel space for further knowledge, wisdom and grow to go up higher levels and experience new ecstasy in the brain....new maturing, growth and development....it is a journey....till end of life....!!!...rams...
