Internally I am a hermit, and externally I am a prince. Arms mean protection to the poor and destruction of the tyrant. Baba Nanak had not renounced the world but had renounced maya, that is, self and ego.
As you are externally aware, so also you can be inwardly aware of your thoughts and feelings, of your motives and urges, of your prejudices, envies, greed and pride…This outward and inward awareness is a unitary process which brings about a total integration of human understanding.
An ignorant man committing evil deeds does not realise the consequences. The imprudent man is consumed by his own deeds, like one burnt by fire.
What counts in life is not the mere fact that we have lived. It is what difference we have made to the lives of others that will determine the significance of the life we lead.
