I don't think simran means meditation, but contemplation. Hindus meditate and repeat phrases over and over again and get into a hypnotic trance. Sikhs reflect on the meanings of any teaching in Guru Granth Sahib, then they become relaxed, shukh sehaij shant. I don't think Waheguru is God's name. Waheguru is a phrase of deep meaning. Wa, wow and he, is and gu, darkness and ru, enlightner. Perhaps the gurus never said "waheguru" this appears the first time in Sewayee Mehela 4 ang 1396. The Bhats poets, didn't they compose this shabad, or someone else who was not a Sikh. Perhaps they were Hindu poets competing with each other. Anyway, simran naam is not repeating a name over and over again. To me, it is repeating the infinite various teachings of Gurbani. As we learn a little every day, we reflect, we take time out from our material concerns and concentrate of the realm of reality. We begin to recognize the hukam natural laws of God in a new or deeper way. We need to explore the meanings of simran, araadh, dhiaya, drllant, and jap. Who are we to give God a name? He doesn't need a name. We give Him a name in order to define what is impossible to describe. God is who He is. Wadi wadiayee, jap apey aap. Great is your greatness, you are who you are. Ang 463. And look at Hen, tun hen, tun hovenhaar, ang 724 Being, You are, You causing all to exist. In the Bible, the Torah Exodus chapter 3, Moses, the Hebrew Prophet asked God His name. The response was "Ehye Asher Ehye" and "Yahweh (pronounced Adonai)." Translated means, I am that I am, and Yahweh means the one who was, is, and will be, and causes all to exist. If you want to find God, the best place to start is by accept His hukam. All of nature teaches us this. Guru Granth Sahib is the ideal guide to use to learn how to do this.
