Chapter-1, Verse 11

Ashtavakra Gita Verse 1.11

मुक्ताभिमानी मुक्तो हि बद्धो बद्धाभिमान्यपि। किंवदन्तीह सत्येयं या मतिः सा गतिर्भ वेत्॥११॥

11. He who considers himself free becomes free indeed, and he who considers himself bound remains bound. ‘As one thinks, so one becomes’, is a proverbial saying in this world and it is indeed quite true.

yā matiḥ sā gatiḥ - ‘As we think, so we become’ is a famous saying. If you assert yourself that you are a helpless, weak and desperate creature of passions and impulses, you cannot grow into the higher heights of beauty and strength of your personality. On the other hand to assert our own divine nature constantly and to try to live without compromising this godly status, is to a seeker the royal path for gaining Self unfoldment.

The Bhagavad-Gītā also uphold this thought:
mana eva manuṣyāṇām kāraṇaṁ bandhamokṣayoḥ. (“Bondage and liberation are decided by the state of the mind.” - Bhagavad-Gītā 12.8)

In the Yogavāsiṣṭha also we find a very similar statement most emphatically put.
yat cittaṁ tanmayo bhavati puruṣaḥ – Yogavāsiṣṭha ("That which one's mind is absorbed in, one becomes")

This is equally true in the spiritual life also, because our apparent illusion of snake has not brought about any change in the rope, which is the only reality therein. Similarly, the pure, infinite Consciousness has never modified Itself, ever into the experiencing ego, nor into the experienced world of plurality. From the delusion created vāsanās in us, desires gurgle forth, which express as thoughts and the thoughts in the mind project the world of experiences, just as in a dream. Awaker never becomes the dreamer, but during the delusion apparently he suffers the tragedies of his dream. At the non apprehension of the Self, the misapprehensions of the world and its sorrows rise. By asserting our nature as the pure, infinite Consciousness, we can come to awake to this new dimension of Experience Divine.

This thought that "our thoughts create our life" is an original tenet of Indian spiritual philosophy. The same principle created THE SECRET. Those who have read The Secret can now figure out the Source of that Secret!
