This śloka continues the description of the highest inner discovery spoken of in the previous verse. In 6.21, Bhagavān described ātyantika-sukham, absolute happiness, which is beyond the senses and grasped by a subtle buddhi. Now He describes the value and strength of that discovery.

Yaṁ labdhvā means “having gained which.” What is gained here is not a new object. It is not wealth, status, heaven, power, name, or even a special emotional experience. It is the recognition of the Self as fullness. The word “gain” is used because, from the seeker’s standpoint, it feels like the greatest discovery. But technically, the Self was never absent. The gain is the removal of ignorance and the owning up of what was always true.

Then Bhagavān says aparaṁ lābhaṁ manyate na adhikaṁ tataḥ — after gaining this, one does not consider any other gain greater than it. This is a radical statement. In ordinary life, every gain is followed by another desired gain. A child wants a toy. A student wants marks. A worker wants a job. A professional wants promotion. A family wants security. A person with wealth wants recognition. A person with recognition wants influence. The mind keeps saying, “This is good, but something more is needed.”

This endless sense of “something more” comes from the feeling of inner incompleteness. As long as I take myself to be limited, I will search for completion through limited things. But limited things cannot give limitless fullness. Therefore, the search continues.

When the Self is recognized as fullness, the basic search is resolved. This does not mean practical goals disappear. A jñānī may still eat, work, teach, travel, care for others, manage a home, or serve society. But these are no longer attempts to become complete. They are expressions of life, dharma, and compassion. Nothing external is considered a greater gain because nothing external can add fullness to the Self.

The second line gives the strength of this recognition: yasmin sthitaḥ — being established in this. This establishment is important. A passing spiritual mood is not enough. A peaceful meditation experience is not enough. A moment of inspiration is not enough. One must be established in the knowledge: “I am the Self, not the changing body-mind alone. I am fullness.” When this is assimilated, it gives deep stability.

Then Bhagavān says na duḥkhena guruṇā api vicālyate — one is not shaken even by great sorrow. Guru duḥkha means heavy sorrow, intense suffering, a major blow. This may include loss, illness, insult, failure, separation, old age, death of loved ones, or painful life events. The verse does not say such events never occur. It does not say the body will never feel pain or the mind will never register sadness. It says the person is not shaken from the truth.

This is a very important distinction. Vedānta does not make a wise person stone-hearted. If a loved one dies, tears may come. If the body is ill, pain may be felt. If society suffers, compassion may arise. But the person does not collapse into the fundamental error: “I am destroyed. I am incomplete. Life has no meaning. My Self has been damaged.” The sorrow is experienced at the level of the body-mind, but it does not displace Self-knowledge.

A tree with shallow roots is easily uprooted by a storm. A tree with deep roots may lose leaves and branches, but it stands. Similarly, ordinary emotional strength depends on favorable conditions. Vedāntic strength depends on rootedness in the Self. Events may shake the surface personality, but they do not uproot the person from reality.

This verse therefore describes the unshakable value of Self-knowledge. It is the greatest gain because it removes the basic sense of lack. It is the greatest security because it is not destroyed by sorrow. All other gains are finite and vulnerable. Wealth can be lost. Health can change. Relationships can shift. Reputation can fall. Achievements can be forgotten. Experiences end. But the Self is the ever-present reality in whose presence all gain and loss are known.

Therefore, the wise person does not say, “I need nothing at all for living.” Rather, he knows, “Nothing finite can make me more complete as the Self.” That is freedom. That is the highest gain.
