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.

My work is loving the world. Here the sunflowers, there the hummingbird — equal seekers of sweetness. Here the quickening yeast; there the blue plums. Here the clam deep in the speckled sand.
Are my boots old? Is my coat torn? Am I no longer young, and still not half-perfect? Let me keep my mind on what matters, which is my work,
which is mostly standing still and learning to be astonished. The phoebe, the delphinium. The sheep in the pasture, and the pasture. Which is mostly rejoicing, since all ingredients are here,
which is gratitude, to be given a mind and a heart and these body-clothes, a mouth with which to give shouts of joy to the moth and the wren, to the sleepy dug-up clam, telling them all, over and over, how it is that we live forever.
