who had brought the phrase unity in diversity
Unity in diversity The diversity is a permanent human condition. The concept of unity in diversity can be traced back to Sufi philosopher Ibn al-'Arabi (1165–1240), who advanced the metaphysical concept of the "oneness of being" (wahdat al-wujud), namely, that reality is one, and that God's is the only true existence; all other beings are merely shadows, or reflections of God's qualities.[5] Abd al-Karīm al-Jīlī (1366–1424) expanded on Al-'Arabi's work, using it to describe a holistic view of the universe which reflects "unity in diversity and diversity in unity" (al-wahdah fi'l-kathrah wa'l-kathrah fi'l-wahdah).[2]
