raga-dvesa-vimuktais tu visayan indriyais charan। atma-vasyair vidheyatma prasadam adhigacchati॥ 2.64 ॥

But a human being free from all attachment and aversion and able to control his senses through regulative principles of freedom can obtain the complete mercy of the Sri.

prasade sarva-duhkhanam hanir asyopajayate। prasanna-cetaso hy asu buddhih paryavatisthate॥ 2.65 ॥

For one thus satisfied in God, the threefold miseries of material existence exist no longer; in such satisfied consciousness, one’s intelligence is soon well established.

nasti buddhir ayuktasya na chayuktasya bhavana। na chabhavayatah shantir asantasya kutah sukham॥ 2.66 ॥

One who is not connected with the God can have neither transcendental intelligence nor a steady mind, without which there is no possibility of peace. And how can there be any happiness without peace?

indriyanam hi charatam yan mano ’nuvidhiyate। tad asya harati prajnam vayur navam ivambhasi॥ 2.67 ॥

As a strong wind sweeps away a boat on the water, even one of the roaming senses on which the mind focuses can carry away a man’s intelligence.

tasmad yasya maha-baho nigrhitani sarvasah:। indriyanindriyarthebhyas tasya prajna pratisthita॥ 2.68 ॥

Therefore, O Arjuna, one whose senses are restrained from their objects is certainly of steady intelligence.

ya nisa sarva-bhutanam tasyam jagarti samyami। yasyam jagrati bhutani sa nisa pasyato muneh:॥ 2.69 ॥

What is night for all beings is the time of awakening for the self-controlled; and the time of awakening for all beings is night for the introspective sage.
