Krishna starts answering Arjuna's question in 2.54 (Kim Vrajeta) VEDABASE LINK   रागद्वेषविमुक्तैस्तु विषयनिन्द्रियैश्चरन् । आत्मवश्यैर्विधेयात्मा प्रसादमधिगच्छति ॥ ६४ ॥ rāga-dveṣa-vimuktais tu viṣayān indriyaiś caran ātma-vaśyair vidheyātmā prasādam adhigacchati Synonyms rāga  — attachment;  dveṣa  — and detachment;  vimuktaiḥ  — by one who has become free from;  tu  — but;  viṣayān  — sense objects;  indriyaiḥ  — by the senses;  caran  — acting upon;  ātma - vaśyaiḥ  — under one’s control;  vidheya - ātmā  — one who follows regulated freedom;  prasādam  — the mercy of the Lord;  adhigacchati  — attains. Translation But a person free from all attachment and aversion and able to control his senses through regulative principles of freedom can obtain the complete mercy of the Lord.   How does a devotee engage his senses in this world? *Krishna gives a key point - Raga Dvesha Vimukteshu. No attachment and No aversion while moving about in this world.* A female patient in terminal stage if she starts liking the male nurse that is a problem because her last thoughts will revolve around him - Raga. At the same time if she starts hating the male nurse (some women naturally don't like males) then this is also a problem because her last thoughts revolve around him (negative thoughts though) - Dvesha. Both cases she will die thinking of him and will take birth again as a Male mostly Karma willing.
