But that knowledge which clings to a single object as if it were the whole, which is without reason, not grounded in truth, and trivial, is declared to be tāmasic (of the nature of ignorance).

Detailed Meaning
Introduction
Here Lord Krishna describes <em>tāmasic</em> knowledge. It is the narrow understanding that clings to one small thing as if it were the whole of reality, without reason, without grounding in truth, and without real insight.
Essence
The knowledge that has closed itself
The third form of knowledge is the most limited. Where sāttvic knowledge sees the whole and rājasic knowledge sees the many, tāmasic knowledge sees only a fragment, and treats it as everything.
Ekasmin kārye saktam (clinging to a single effect or object): The mind fixes itself on one thing, whether an idea, an object, a ritual, a belief, or a habit, and refuses to look beyond it.
Kṛtsnavat (as if it were the whole): This small portion is mistaken for the entire truth. The person thinks, This is all there is.
Ahaitukam (without reason): The attachment is not based on reasoning or inquiry. It is held out of habit, fear, or inertia.
Atattvārtha-vat (without grasping the real truth): It has no relation to the true nature of things. It is a conviction without insight.
Alpaṁ ca (and trivial): Finally, Lord Krishna calls it alpa, small or petty. The knowledge is confined, shallow, and unproductive.
What does this look like in practice?
Fanaticism is a clear example, in which one belief is defended as the whole truth and every other perspective is rejected without examination. But the same quality appears in quieter ways, such as the person who is absorbed only in one narrow concern, refusing to learn or to question, or who treats a single bodily comfort or possession as the entire purpose of life.
The difference between this and sāttvic knowledge is stark. Sāttvic knowledge expands the heart and mind, while tāmasic knowledge contracts them.
Message for Everyday Life (Staying Open to Inquiry)
All of us have fixed ideas that we have never examined. They may be about people, about money, about success, or about ourselves.
A practice: Pick one strong opinion you hold and ask, Why do I believe this, and what might I be missing? Willingness to question protects the mind from this narrowness.
