वसति हृदि सनातने च तस्मिन्भवति पुमाञ्जगतोऽस्य सौम्यरूपः ।क्षितिरसमतिरम्यमात्मनोऽन्तः कथयति चारुतयैव सालपोतः ॥
In plain words
Live in that eternal heart, and you become gentle to look at, gentle to be near — the whole world feels it. A young sāla tree does the same: it never says a word about the sweet sap it has drawn up out of the earth and holds inside, yet its beauty alone tells you everything.
Close to the Sanskrit
And when he dwells in that eternal heart, a man becomes gentle in form for this world — just as the sāla sapling declares, by its loveliness alone, the exceedingly sweet earth-sap that is within itself.
