B.G 2.62 and 63
ध्यायतो विषयान् पुंसः सङ्गस्तेषूपजायते। सङ्गात् सञ्जायते कामः कामात् क्रोधोऽभिजायते॥६२॥
क्रोधाद्भवति सम्मोहः सम्मोहात् स्मृतिविभ्रमः। स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात् प्रणश्यति ॥६३॥
dhyāyatō viṣayān puṁsaḥ saṅgastēṣūpajāyatē। saṅgāt sañjāyatē kāmaḥ kāmāt krōdhō'bhijāyatē॥62॥
krōdhādbhavati sammōhaḥ sammōhāt smr̥tivibhramaḥ। smr̥tibhraṁśād buddhināśō buddhināśāt praṇaśyati ॥63॥
When the person dwells on material topics, he develops attachment in them. From attachment springs desire. From that desire comes forth the anger. Anger results in the inability to discriminate. Loss of discrimination results in the distortion of memory. The distorted memory destroys the knowledge. He perishes from the destruction of knowledge.
Gīta Tātparya 2.62 and 63
'saṁmōhā' - means wrong knowledge
'saṁmōhāt' - means wrong knowledge, i.e. even after understanding thinking otherwise. Because of mind's attention on something else, knowledge to decipher the meaning of the sentence is lost.
