Here is a very rich and foundational thought, also from Rabbi Yisroel. It jumps out of the praise of God that’s found in the scriptures.
The first step in a relationship with the Creator of all is the simple recognition that I only exist as an expression of His love, and that every other being that I could encompass with my five senses, also, only exists as an expression of His love.
All of our love and all of our devotion together with the love and devotion of every other being who dwells under God’s heaven belongs to the One who loved us all into being. Our hearts belong to our Father, the One who spread these heavens and established this earth – and to no one else.
