Mandukya Karika 2.4
Sanskrit Verse
अन्तःस्थानात्tu भेदानां तस्माज्जागरिते स्मृतम् ।
यथा तत्र तथा स्वप्ने संवृतत्वेन भिद्यते ॥ ४ ॥
Transliteration
antaḥsthānāttu bhedānāṃ tasmājjāgarite smṛtam |
yathā tatra tathā svapne saṃvṛtatvena bhidyate || 4 ||
Translation
Different objects cognized in dream (are illusory) on account of their being perceived to exist. For the same reason, the objects seen in the waking state are illusory. The nature of objects is the same in the waking state and dream. The only difference is the limitation of space (associated with dream objects).
Mandukya Karika 2.6
Sanskrit Verse
आदावन्ते च यन्नास्ति वर्तमानेऽपि तत्तथा |
वितथैः सदृशाः सन्तोऽवितथा इव लक्षिताः || 6 ||
Transliteration
ādāvante ca yannāsti vartamāne’pi tattathā |
vitathaiḥ sadṛśāḥ santo’vitathā iva lakṣitāḥ || 6 ||
Translation
That which is non-existent at the beginning and in the end, is necessarily so (non-existent) in the middle. The objects are like the illusions we see, still they are regarded as if real.
Mandukya Karika 2.7
Sanskrit Verse
सप्रयोजनता तेषां स्वप्ने विप्रतिपद्यते ।
तस्मादाद्यन्तवत्वेन मिथ्यैव खलु ते स्मृtaः ॥ ७ ॥
Transliteration
saprayojanatā teṣāṃ svapne vipratipadyate |
tasmādādyantavatvena mithyaiva khalu te smṛtāḥ || 7 ||
Translation
The serving a purpose (as means to an end), of them (the objects of waking experience) is contradicted (opposed) in dream. Therefore they are undoubtedly admitted to be illusory on account of their (both waking and dream) being with a beginning and an end.
Mandukya Karika 2.12
Sanskrit Verse
कल्पयत्यात्मनाऽऽत्मानमात्मा देवः स्वमायया |
स एव बुध्यते भेदानिति वेदान्तनिश्चयः ॥ १२ ॥
Transliteration
kalpayatyātmanā”tmānamātmā devaḥ svamāyayā |
sa eva budhyate bhedāniti vedāntaniścayaḥ || 12 ||
Translation
Ātman, the self-luminous, through the power of his own Māyā, imagines in himself by himself (all the objects that the subject experiences within or without). He alone is the cognizer of the objects (so created). This is the decision of the Vedānta.

niyatāṃśca bahiścitta evaṃ kalpayate prabhuḥ || 13 ||
Translation
The Lord (Ātman), with his mind turned outward, variously imagines the diverse objects (such as sound, etc.), which are already in his mind (in the form of Vāsanas or Saṅkalpas or desires). The Ātman again (with his mind turned within), imagines in his mind various (objects of) ideas.

Transliteration
avyaktā eva ye’ntastu sphuṭā eva ca ye bahiḥ |
kalpitā eva te sarve viśeṣastvindriyāntare || 15 ||
Translation
Those that exist within the mind (as mere subjective imaginations) and are known as the unmanifested as well as those that exist without in a manifested form (as perceived objects),—all are mere imaginations, the difference lying only in the sense-organs (by means of which the latter are cognized).
Mandukya Karika 2.29
Sanskrit Verse
यं भावं दर्शयेद्यस्य तं भावं स तु पश्यति ।
तं चावति स भूत्वासौ तद्ग्रहः समुपैति तम् ॥ २९ ॥
Transliteration
yaṃ bhāvaṃ darśayedyasya taṃ bhāvaṃ sa tu paśyati |
taṃ cāvati sa bhūtvāsau tadgrahaḥ samupaiti tam || 29 ||
Translation
He (the inquirer) cognizes only that idea that is presented to him. It (Ātman) assumes the form (of what is cognized) and thus protects (the inquirer). Possessed by that (idea) he realises it (as the sole essence).
