The moment you become attached to the phenomena you create, you enter the stream of chaos. However, if you can realize the nature of the mind by letting go of the phenomena, you will experience nirvana in each moment.
If you chase after superficial phenomena, you will find chaos. However, if you do not follow the phenomena, nirvana will be revealed to you. Nirvana is already here in this moment. Just do not hold on to the phenomena that you have created.
