Shiva Purana
वस्तुतस्तु स्वयं सर्वं क्रमो हि भासते शुभः॥ अज्ञानं च मतेर्भेदो नास्त्यन्यच्च द्वयम्पुनः॥ ८॥
Really Śiva alone, the auspicious being, manifests himself. The ignorance of the same is a defect of the mind. In fact there is no second entity.
english translation
vastutastu svayaM sarvaM kramo hi bhAsate zubhaH॥ ajJAnaM ca materbhedo nAstyanyacca dvayampunaH॥ 8॥
