Our own plain rendering: Mastery of the mind is attained when it can focus with equal ease on everything from the smallest atom to the greatest infinity.

The Sign of Mastery

Patanjali concludes this section by describing the hallmark of a mind that has overcome the obstacles: vaśīkāraḥ (mastery or control). This mastery is defined by the mind's range. A trained mind is not one that can only focus on "spiritual" things; it is a mind that can settle on the paramāṇu (the smallest particle/atom) or the parama-mahattva (the greatest magnitude/infinity) without wavering. Vyasa explains that this indicates the mind has become completely transparent and unburdened by the antarāyāḥ. It can now move between the microscopic and the macroscopic with total agility.

The Transparency of the Citta

In classical yoga, a mastered mind is like a high-quality lens. Whether you point it at a tiny insect or a vast galaxy, the focus remains sharp. Vachaspati Mishra notes that this state of vaśīkāraḥ is the prerequisite for the samāpattis (absorptions) that will be discussed in the following sutras. The mind no longer gets "stuck" or "distracted" by the scale of the object. This reflects the yogic view that the citta is essentially all-pervasive (vibhu) and its apparent limitations are only due to its identification with the gunas. When the vikṣepas are removed, the mind's natural capacity is restored.

Agility and Stability

Edwin Bryant observes that this sutra highlights the scientific and objective nature of Patanjali's yoga. It's about the functionality of consciousness. A yogi who has attained this level of mastery is not just a "meditator" in a cave; they are someone who can apply full, undivided attention to any task or object. I.K. Taimni describes this as the "full range of the mind." This mastery is the bridge to the higher stages of samādhi, where the mind will eventually dissolve its own boundaries to realize the Purusha. It is the final confirmation that the practices from 1.32 to 1.39 have been successful.

Developing Mental Agility

This practice involves training the mind to switch between different scales of focus, maintaining the same quality of presence in each.

The Six-Step Practice of Scaling Focus

1. Micro-Focus: Choose a tiny object (like the tip of a needle or a single grain of sand). Focus all your attention on its details for two minutes.
2. Expansion: Slowly expand your focus to the room you are in. Try to be aware of the entire space at once, without losing the clarity you had with the tiny object.
3. Macro-Focus: Shift your awareness to the idea of the vast sky or the entire planet. Hold this sense of "infinity" (parama-mahattva) for two minutes.
4. Return to Center: Bring the focus back to a mid-point, such as your own breath.
5. Observing the Ease: Notice if the mind resists the change in scale. Mastery is when the transition is seamless and the focus remains equally steady.
6. Resting in Vaśīkāra: Spend the final minutes of your practice not focusing on any scale, but resting in the capacity of your mind to focus on anything.

The Ego Trap of 'Mastery'

A common misreading is to think that vaśīkāraḥ means the ego has gained power over the world. In classical yoga, "mastery" refers to the citta's ability to stay focused, not the person's ability to manipulate physical matter. It is a state of internal discipline, not external domination. Swami Vivekananda cautioned that the desire for power is the greatest obstacle to real progress.

Confusing Focus with Intellectual Understanding

Another error is to think that focusing on the "atom" means understanding nuclear physics. Patanjali is talking about dhyāna—the meditative absorption into the object's essence—not an intellectual analysis of its properties. Georg Feuerstein noted that a scientist might know everything about an atom but still have a highly distracted mind (vikṣipta). The yogic mastery is about the steadiness of the consciousness, regardless of the object's complexity or size.
