pramādāt

सखेति मत्वा प्रसभं यदुक्तं हे कृष्ण हे यादव हे सखेति

prasabham — presumptuously

For whatever I said to you carelessly, thinking you a friend — “Krishna”, “Yadava”, “my friend” — not knowing your greatness,

सत्त्वं सुखे सञ्जयति रजः कर्मणि भारत

pramāde — to delusion

अप्रकाशोऽप्रवृत्तिश्च प्रमादो मोह एव च

pramādaḥ — negligence

Darkness, inactivity, heedlessness and delusion arise when inertia has grown strong, Arjuna.
