To me, sadhana is a daily spiritual practice allowing time and space for an individual to turn inward.
As Yogi Bhajan (of the Kundalini yoga tradition) says, "Sadhana is self-enrichment. It is not something which is done to please somebody or to gain something. Sadhana is a personal process in which you bring out your best."
Sadhana could be taking a walk in nature, doing breath work or yoga asanas on a mat, spending time meditating or chanting, reading and reflecting on a poem, or simply watching the sun rise.
Please accept this post as a possible starting point for your own practice today, including, "When Death Comes," a poem by Mary Oliver, who celebrated her 80th birthday this past week.
When death comes like the hungry bear in autumn; when death comes and takes all the bright coins from his purse
to buy me, and snaps the purse shut; when death comes like the measle-pox;
when death comes like an iceberg between the shoulder blades,
I want to step through the door full of curiosity, wondering: what is it going to be like, that cottage of darkness?
And therefore I look upon everything as a brotherhood and a sisterhood, and I look upon time as no more than an idea, and I consider eternity as another possibility,
and I think of each life as a flower, as common as a field daisy, and as singular,
and each name a comfortable music in the mouth, tending, as all music does, toward silence,
and each body a lion of courage, and something precious to the earth.
When it’s over, I want to say: all my life I was a bride married to amazement. I was the bridegroom, taking the world into my arms.
When it’s over, I don’t want to wonder if I have made of my life something particular, and real.
I don’t want to find myself sighing and frightened, or full of argument.
I don’t want to end up simply having visited this world.
