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.
Eagle Poem, from In Mad Love and War, by Joy Harjo
To pray you open your whole self
To sky, to earth, to sun, to moon
To one whole voice that is you.
And know there is more
That you can’t see, can’t hear;
Can’t know except in moments
Steadily growing, and in languages
That aren’t always sound but other
Circles of motion.
Like eagle that Sunday morning
Over Salt River. Circled in blue sky
In wind, swept our hearts clean
With sacred wings.
We see you, see ourselves and know
That we must take the utmost care
And kindness in all things.
Breathe in, knowing we are made of
All this, and breathe, knowing
We are truly blessed because we
Were born, and die soon within a
True circle of motion,
Like eagle rounding out the morning
Inside us.
We pray that it will be done
In beauty.
In beauty.
