Shiva Purana
द्विखंडं तु चरां लिंगं कुर्वन्त्यज्ञानमोहिताः । नैव सिद्धान्तवेत्तारो मुनयः शास्त्रकोविदाः ३३ ।
Only those who are deluded by ignorance make the mobile phallic image of two pieces. The sages who know the Śaiva cult; and are well versed in Śaiva Sacred texts do not enjoin that.
english translation
