# SB 7.15.63 > कार्यकारणवस्त्वैक्य दर्शनं पटतन्तुवत > अवस्तुत्वाद्विकल्पस्य भावाद्वैतं तदुच्यते ॥६३॥ ## Text > kārya-kāraṇa-vastv-aikya- > darśanaṁ paṭa-tantuvat > avastutvād vikalpasya > bhāvādvaitaṁ tad ucyate ## Synonyms *kārya*—the result or effect; *kāraṇa*—the cause; *vastu*—substance; *aikya*—oneness; *darśanam*—observation; *paṭa*—the cloth; *tantu*—the thread; *vat*—like; *avastutvāt*—because of being ultimately unreality; *vikalpasya*—of differentiation; *bhāva-advaitam*—the conception of oneness; *tat ucyate*—that is called. ## Translation **When one understands that result and cause are one and that duality is ultimately unreal, like the idea that the threads of a cloth are different from the cloth itself, one reaches the conception of oneness called bhāvādvaita.**
