Analysis of Thou alone could know

I am like a stone segment, gyrating in the stream, where it will stop, where it will reach, thou alone know.
Where, when and how thou will take me with the time, where there is a godsend crept in, where there is a ruin hideaway, thou alone know.
At times thou pickest me up in the broken boat, at times thou pickest me up in the chariot of joy, my ignorant mind starts doubting thy care with me, it sits and  stupidly judges ; Anything without know.
Hey Lord, should anything is to know, thou art  thee who alone could know.
