Our own plain rendering: To counteract these obstacles and their symptoms, one should practice focus on a single principle.

The Remedy: One-Pointedness

After detailing the obstacles and symptoms, Patanjali offers a singular, elegant solution: eka-tattva-abhyāsaḥ—the practice of a single truth or principle. The "tat" (that) in the sutra refers back to the obstacles and symptoms previously mentioned. To prevent (pratiṣedha) them from taking root, the practitioner must train the mind to stay on one object. Vyasa argues that this sutra proves the mind is not just a collection of fleeting ideas (as some Buddhist schools held) but a continuous entity that can be stabilized on a single point. If the mind were only a series of moments, there would be no "one" to practice on "one" thing.

Defining the Single Principle

What is this eka-tattva? Traditional commentators offer various interpretations. Vachaspati Mishra suggests it could be the Īśvara mentioned earlier, while others suggest any stable object of meditation. The key is not necessarily what the object is, but the constancy of the focus. In classical yoga, the fragmentation of the mind is the problem; therefore, integration (samādhi) is the cure. Vijnanabhikshu emphasizes that the practice must be sustained and uninterrupted. By choosing one principle and returning to it every time an obstacle arises, the practitioner builds the "mental muscle" necessary to override the habit of distraction (vikṣepa).

The Psychological Impact of Eka-Tattva

The power of eka-tattvābhyāsa lies in its ability to starve the obstacles of attention. Edwin Bryant notes that the obstacles thrive on a wandering mind. When the mind is occupied with a single, positive, or neutral focus, the seeds of doubt, laziness, and despair cannot sprout. I.K. Taimni describes this as the "law of substitution." Instead of fighting the obstacles directly, which often gives them more energy, we substitute the distracted state with a concentrated one. Over time, this practice reconfigures the saṃskāras (subliminal impressions) of the mind, making one-pointedness the new default state rather than distraction.

Implementing One-Pointed Focus

This practice is the foundational training of the yogic mind. It requires choosing an object and committing to it for the duration of the practice session.

The Six-Step Practice of Eka-Tattva

1. Choose Your Object: Select a single point of focus. It could be the breath, a mantra, a visualization, or a physical object. Ensure it is something you can return to easily.
2. Set a Duration: Commit to a specific timeframe (e.g., 10 or 20 minutes) during which you will not change your object.
3. Gentle Re-entry: Every time the mind wanders to one of the nine obstacles (like a doubt or a memory of pain), gently and firmly bring it back to the eka-tattva.
4. Avoid Variety: Resist the urge to switch objects because you are bored. Boredom is often a form of styāna (mental dullness) or avirati (desire for novelty).
5. Deepening the Connection: As you stay with the object, try to perceive its subtler qualities. If it's the breath, feel the texture; if it's a mantra, feel the resonance.
6. Closing Observation: At the end of the session, notice if the symptoms of vikṣepa (like irregular breath or agitation) have diminished.

The Mistake of 'Multi-tasking' Yoga

A common misreading in modern life is that one can practice yoga while also engaging in other mental activities. Classical yoga is emphatic: eka-tattva means one. You cannot be practicing the sutras while listening to a complex podcast or planning your day. Swami Satchidananda warned that a divided mind is a distracted mind, and a distracted mind cannot reach samādhi. The "single principle" requires total engagement.

Misunderstanding the Object

Some practitioners get caught in "analysis paralysis," trying to find the "perfect" object for their eka-tattvābhyāsa. The effectiveness of the practice comes from the abhyāsa (repetition/effort), not from a magical quality of the object itself. Georg Feuerstein noted that the specific object is less important than the quality of the attention given to it. Switching objects frequently is actually a manifestation of vikṣepa, not a solution to it.
