About this I just know one thing – unless one leads herself/ himself cannot lead others.
Also, unless one masters the virtue of humility to a certain degree, which would allow him or her to be a servant of love to every single human being, one cannot be a leader in true sense.
I think, self denial is the key. I know not much about this. May the Divine Wisdom enlighten our hearts to be holy on a daily basis. Holiness follows humility. Humility makes us leaders holding the light in stretched out hands, to help others see the way, which we are set to follow ourselves. Divine Master may we follow you with the light and the daily cross of self-denial daily, until we complete our life’s journey. Amen.
