The windows in our lives open and close, or they seem to. When they're open, our fountain of love and joy appears inexhaustible. Other times, even finding a drop of water can feel like crossing an endless desert. So we do the spiritual practice that's there at that time, with a kind heart toward ourselves, and all others, whatever the scope. We are all beginners stuck in samsara. So we persevere. "Never give up!" His Holiness the Dalai Lama reminds.
Perhaps we can commit to cultivate kindness and compassion for an hour. Or for just a minute. Or just the next 10 seconds - or one second! Maybe once a day! Even for this, all the holy beings rejoice. Bodhisattva for a moment! Slowly, slowly.
This life is like a dream, from sleep to sleep again and again, fooled by the appearances of the sense objects - the forms, sounds, etc., believing them to be real, permanent. Soften the heart. Soften the eyes. Practicing kindness toward others makes real what words can only point to. Reflecting on interdependence, or "emptiness" as the label goes, is the same! To do so with an eye toward offering others relief from their suffering is an act of such love and kindness.
So Shantideva says -
So take advantage of this human boat.
Free yourself from sorrow's mighty stream!
This vessel will be later hard to find.
And therefore ...
The time that you have now, you fool, is not for sleep!
So we do the practice.
