श्रीभगवान्
In plain words
The Blessed Lord said: Partha, there is no destruction for that person either here or hereafter. No one who does good, dear one, ever comes to a bad end.
Word for word
O son of Pṛthā, neither here nor hereafter is there ruin for him at all; for no doer of good, dear one, goes to a bad end.
पार्थ नैवेह नामुत्र विनाशस्तस्य विद्यतेन हि कल्याणकृत् कश्चिद् दुर्गतिं तात गच्छति

▸Bhagavadgītābhāṣyam· bhāṣya
हे पार्थ नैव इह लोके नामुत्र परस्मिन् वा लोके विनाशः तस्य विद्यते नास्ति । नाशो नाम पूर्वस्मात् हीनजन्मप्राप्तिः स योगभ्रष्टस्य नास्ति । न हि यस्मात् कल्याणकृत् शुभकृत् कश्चित् दुर्गतिं कुत्सितां गतिं हे तात, तनोति आत्मानं पुत्ररूपेणेति पिता तात उच्यते । पितैव पुत्र इति पुत्रोऽपि तात उच्यते । शिष्योऽपि पुत्र उच्यते । यतो न गच्छति ॥ ४० ॥
In plain words
‘O Pārtha, destruction exists for him neither here in this world, nor there in the other.’ ‘Destruction’ here means being reborn into a lower birth than before—and that never happens to someone fallen from yoga. Because no one who does good, who does what is auspicious, ever comes to a wretched end, dear one. (The word for ‘dear one,’ tāta, is used because a father extends himself into his son—so a father is called tāta; and since a father is really his son, the son too is called tāta; and a disciple, too, is called a son.) Because he simply doesn't go there.
Close to the Sanskrit
‘O Pārtha, not at all here in this world, nor there in the other world, does destruction exist for him.’ ‘Destruction’ namely means the attainment of a lower birth than the former one; that does not exist for one fallen from yoga. For, because no doer of good, i.e. doer of the auspicious, goes to an evil destiny, i.e. a wretched destiny, O dear one’—the term ‘tāta’ is used because a father extends himself in the form of a son, thus a father is called ‘tāta’; since the father is indeed the son, the son too is called ‘tāta’; the disciple too is called ‘son.’ Because he does not go there.
