Shri Rama Gita
अकारसंज्ञः पुरुषो हि विश्वको ह्युकारकस्तैजस ईर्यते क्रमात् । प्राज्ञो मकारः परिपठ्यतेऽखिलैः समाधिपूर्वं न तु तत्त्वतो भवेत् ॥ ४९॥
The rishis of the Vedic period declare that a-kara represents the waker, u-kara represents the dreamer, and ma-kara, the deep sleeper, and all their respective experiences. These distinctions are all valid only before samadhi, never in the absolute nature of reality.
