As per the Quran, why did God create things in pairs?

[Shri Anil asked: Surah Yasin 36: Glory be to the One Who created all ˹things in˺ pairs—˹be it˺ what the earth produces, their genders, or what they do not know! Swami as per the Quran why did God create things in pairs?]

Swami replied:- “Marriages are made in heaven” is the background saying of this concept. This means that when a pair selects each other and gets married, elders say that their marriage was already done by God in heaven even before they were born here. The final essence is that the marriage takes place only by the will of God. Hence, in spite of the hectic efforts of the parents, marriages are not settled and finally get settled only by the will of God. Marriage is only an example. Any effort gets success in this world only if God approves it. This is the final message of this statement.
