Sankaracarya's Vivekachudamani 479

स्वानुभूत्या स्वयं ज्ञात्वा स्वमात्मानमखण्डितम् ।

संसिद्धः संमुखं तिष्ठेन्निर्विकल्पात्मनात्मनि ॥

svānubhūtyā svayaṃ jñātvā svamātmānamakhaṇḍitam |

saṃsiddhaḥ saṃmukhaṃ tiṣṭhennirvikalpātmanātmani ||

(Sankaracarya's Vivekachudamani 479)

Knowing one‘s own Absolute Self through Realization, becoming perfect, one should stand face to face before the Self, with a mind free from all concepts of dualism.

The mind is our central sense. Our five gross senses—sight, hearing, taste, touch, and smell—send the mind information, which the mind judges as either agreeable or disagreeable. Typically, the mind makes its judgments based on false ego, the misconception that we are our bodies, and the assumption that we can find lasting happiness by gaining control over the material world. The mind constantly calculates how to find and sustain pleasure and how to avoid discomfort, and sends us signals—thoughts—how to do so.

But the material world is an endless, unpredictable mix of pleasant and unpleasant circumstances, and when we act on the mind's decisions, our happiness isn't guaranteed. The mind can't lead us toward genuine fulfillment of any kind. For us to succeed in any significant endeavor, especially anything involving long-term, goal-directed activity, the mind must be trained to make judgments that support that success. One should truly understand that he is a soul and face the reality. Only by knowing the truth, one can attain perfection. There is no question of enjoying the bodily conception and try to know the soul. There is no dualism in this. One should focus only on knowing the Atma more deeply, that is called transcendental understanding.
