Whatever our mistakes and errors that led to our present distress, our present lack of choice, we can only err by ignoring the reality of our situation: for whatever slight chance of success, it is proper to seek that success rather than embrace certain failure. What other choice does a Yogi have but to respond to the complaint (or antagonism) of Sudarshana by trying to correct their faults - or at least become capable of doing so?
There are many examples of when we must make the best of a very bad situation - and accept that success is improbable.
It is similar to how a building may be constructed improperly, whether by improper architecture or improper engineering. It is so impracticable to correct these problems after construction is done that we say it is infeasible and impossible, and the building must be used despite its many faults. Then, the Nivaran Sudarshan Yantra is practiced to confront those errors in architecture which cannot be corrected.
The mantra for a Nivaran Sudarshan Yantra is the Mahamrityunjaya Mantra, which expresses this same philosophy, the non-choice for resolute optimism necessary in the face of likely failure: it is reasonable and logical to hope that some good may come of our effort, despite the small chance of success, and despite our many faults.
2. The Yogi then surrounds themselves with the proper invocation (om shrim hrim klim), om to the north, shrim to the east, hrim to the south, krim to the west.
3. The Yogi faces east and north and draws a square.
4. At the north corner of this first square (3), the Yogi draws another.
5. Sharing the southeast side of the square, the Yogi draws another (5)
6. Skipping the space required for a square on the northeast side of square 5, the Yogi draws a square (6); notice the desire to connect this gap, the failure to reach it - the next squares will build toward it, as we build upon our own foundations; like this square, if our goal is perfectly and properly aligned, it is easier to reach it.
7. Sharing the northeast side of the first square (3), the Yogi draws a square (7)
8. The Yogi then draws a square with its sides aligned north and south, east and west, with the western corner placed at the northern corner of square 3 (the western corner of square 7): this is square 8, the symbolic handle of the chakra, both the altar of warrior's weapon, and of this yantra; symbolic of the intersection of wind and earth
9. Sharing the southeast side of square 7, the Yogi draws a square (9)
10. Sharing the southwest side of square 3, the Yogi draws a square (10)
11. The Yogi then understands: squares 4, 6, and 10 reflect the wisdom of the Three-Eyed (Shiva)...and understands how to achieve the purpose of this wisdom, in completion, in success: just as those numbers, 3 and 5, add to 8, focusing on the altar and the purpose reveals the means of success (12 + 5 + 3 = 20).
12. Sharing the southeast side of square 5, the Yogi completes the yantra by drawing a square (12).
The numbers in any length of the chakra add to 20, symbolic of the moon; square 8, representing the handle of the chakra, the solar eclipse and its wind, adds to 28, the length of a moon, and symbolizing 0, the strength of the logical process of negation in truth or honor - as the solar eclipse strengthens the honor of the moon.
Om om om.
There are other ways to use this yantra, and other contemplations and understandings to gain from it, but this is a good beginning.
Place a leaf on the altar, to honor Ganesh. Someone without tears or sweat left, someone without anything left to say or voice to say it, or who cannot speak, or does not know how, has no choice but to choose (ni-vr) to use a drop of water for that leaf, to nourish the wind to speak on their behalf of what was just laid upon the earth...
