The sun continuously sets and rises. We sit calmly, as time moves on.
How do we deal with this thing called time?
Should we be active? Should we relax?
The Lubavitcher Rebbe never took a day of vacation.
Every minute, to him, was precious. Every second counted, and he made the most of it.
At farbrengens (Chasidic gatherings) he talked for hours (revealing insights in Torah and perspectives on life), interspersed with joyous song. Yet the Rebbe seemed to be an oasis of calm and serenity, even as he led a revolution to create a better world.
The Rebbe taught us how to use the entire world, including attributes of calm and energy, to passionately achieve goodness.
You can be calm and quiet, while you think about how to help others. You can be lost in thought, for the purpose of understanding more and thereby achieving more.
And you can be actively involved in achieving things, while maintaining inner composure and peace of mind.
Time. It beckons. And it can be full of purpose.
We need only to know how to use it.
