Chapter-15, Verse 16

Aṣṭāvakra Gita Verse 15.16

तवैवाज्ञानतो विश्वं त्वमेकः परमार्थतः । त्वत्तोऽन्यो नास्ति संसारी नासंसारी च कश्चन ॥ १६ ॥

It is through your ignorance that all this exists. In reality you alone exist. Apart from you there is no one within or beyond samsara.

This Verse is a profound statement on the nature of existence and the Self. It suggests that all of creation exists only because of our ignorance, and that in reality, only the Self exists. The Verse goes on to say that there is no one else within or beyond samsara, which can be interpreted as a statement on the interconnectedness of all things.

The Ashtavakra Gita is a text belonging to the Advaita Vedanta school of orthodox Indian philosophy, and it shares many similarities with other Vedic texts. 

The Brihadaranyaka Upanishad (1.4.10) asks similar questions about the nature of existence and the Self.

यतो वा इमानि भूतानि जायन्ते ।

तत्र को मोहः कः शोक एकत्वमनुपश्यतः ॥

From where do these beings come into existence? And where do they go after death? Who sees them as one and undivided?

The Katha Upanishad (2.1.11) speaks to the idea of an immutable Self that pervades all things.

अविनाशि तु तद्विद्धि येन सर्वमिदं ततम् ।

विनाशमव्ययस्यास्य न कश्चित् कर्तुमर्हति ॥

Know that to be imperishable by which all this is pervaded. None can cause the destruction of this immutable being.

The Bhagavad Gita (6.29) speaks to the idea of seeing oneself in all things and all things within oneself

सर्वभूतस्थमात्मानं सर्वभूतानि चात्मनि ।

ईक्षते योगयुक्तात्मा सर्वत्र समदर्शनः ॥

A yogi who sees Me in everything and sees everything within Me, knows Me as the highest Reality.
