What it is to be a silent witness like a rock in your self journey ?
It doesn’t mean that you have to be emotionless like a rock.
In the self journey, the ROCK represents the complete surrender and the sturdiness it shows when it is in the hands of the sculptor ( Master). With every hit from the master it is sure that the master is carving it to give a better shape.
Such surrender to your master makes you worthy of sitting in a place where one day your master is proud of his effort and he will be the one to adore you and admire you the most.
