Guru Nanak Dev ji with Bhai Mardana ji and local villagers. In the spirit of my old painting – http://www.sikhiart.com/guru-nanak-dev/

How can one realize the truth that all is impermanent?
By staying with the current of the eternal present moment one can recognize things for what they truly are.
What is the eternal present moment?
The eternal present moment cannot be stated, you can only be with it. But know that it is in the present moment in which things take form, in which living beings come to life, in which greatness is obtained, in which one becomes high or low, in which pleasure and pain is received. Everything is happening inside this eternal moment, there is nothing outside of it.
