If our focus of concentration is in the heart and not in the mind, then what comes to the fore will be all sincerity. Inside the heart is the soul, and what comes from the soul cannot be anything but a flood of sincerity. More than that, it is also a flood of spirituality. Through the heart, the soul speaks most powerfully and convincingly.
If we spend more time in our heart than in our mind, then we are bound to know what sincerity is. Inside our heart we have an inner vessel and this vessel is every day filled by God's Purity. There we can grow. When our existence grows there, then we will see that we are collecting a bumper crop of sincerity every day.From:Sri Chinmoy,Perfection and transcendence, Agni Press, 1977
