Chapter-16, Verse 4

Ashtavakra Gita Verse 16.4

व्यापारे खिद्यते यस्तु निमेषोन्मेषयोरपि ।

तस्यालस्यधुरीणस्य सुखं नाऽन्यस्य कस्यचित् ॥ ४ ॥

Happiness belongs to that master idler who feels distressed even at the effort of opening and closing his eyes! It belongs to none else.

The one who is free from all worldly activities and attachments, who has no desire or expectation from anything, who is indifferent to the dualities of pleasure and pain, gain and loss, honor and dishonor, etc., who is content with his own self, who has transcended the sense of ego and individuality, who is established in the Supreme State of non-duality, he alone enjoys the Supreme Bliss that is not dependent on any external factor. 

He is so detached from everything that even the slightest movement of his eyelids seems to be a burden to him. He is not lazy in the sense of being inactive or negligent, but in the sense of being completely relaxed and at ease.

This verse expresses the highest ideal of Advaita Vedanta, which is to realize one's true nature as Brahman, the absolute reality that is beyond all names and forms, attributes and limitations, time and space, cause and effect. The one who realizes this truth becomes free from all bondage and suffering, and attains the state of liberation or moksha. He does not identify with his body, mind, senses, intellect, or any other object of perception, but with his Pure Consciousness that is the Witness of all phenomena. He does not depend on anything for his happiness, but finds it within himself.

There are many similar verses in Vedic literature. 

This verse is from the Bhagavad Gita (5.21):

बाह्यस्पर्शेष्वसक्तात्मा विन्दत्यात्मनि यत्सुखम् । स ब्रह्मयोगयुक्तात्मा सुखमक्षयमश्नुते ॥

He who is not attached to external world finds happiness within himself. He who has his Self united with Brahman through yoga enjoys eternal bliss.

This verse is from the Kaivalya Upanishad (3):

न कर्मणा न प्रजया धनेन त्यागेनैके अमृतत्वमानशुः । परेण नाकं निहितं गुहायां विभ्राजते यद्यतयो विशन्ति ॥

Not by action, nor by progeny, nor by wealth, but by renunciation alone some attained immortality. That which is hidden in the highest heaven shines forth when the seers enter into it.

This verse is from the Isha Upanishad (7):

यस्मिन्सर्वाणि भूतान्यात्मैवाभूद्विजानतः ।

तत्र को मोहः कः शोक एकत्वमनुपश्यतः ॥

He who knows that all beings are nothing but his own Self, where is delusion and where is grief for him who sees oneness everywhere?
