Only those who have loved shall attain the Lord
Guru Gobind Singh in the Dasam Granth in verse number 9 of Tav Prasad Saviaye puts a seal on the concept of Love leading to salvation. Tav Prasad Saviaye is one of the five Banis of a Sikh's daily Nitnem routine of reciting of the Guru's words. In this Bani, the tenth master covers many aspects of human living which one needs to inspect on a daily basic but the central message comes is the concept of "Love for the Lord and his creation" and the constant "remembrance of His Name". If you do not feel any love for God; you will not feel any love for His creation and vice versa; your heart will be barren and you will have no compassion or mercy.
The Guru reminds us:
ਸਾਚੁ ਕਹੋਂ ਸੁਨ ਲੇਹੁ ਸਭੈ ਜਿਨ ਪ੍ਰੇਮ ਕੀਓ ਤਿਨ ਹੀ ਪ੍ਰਭ ਪਾਇਓ ॥੯॥
Sach kahon sun leho sabai jin prem kio tin hee prabh paio.
I tell the truth; listen everyone. Only those who have Loved, will realize the Lord. (9)
The message of Love and longing is evident on all the pages of the Sikh scriptures. The Love for God and His creation is easy to see in Gurbani; the Lord is referred to as "Husband Lord", "Beloved", "Immaculate", "Great", "Merciful", etc. all affectionate words for a tender, caring and powerful being. However, God is not an external entity; God is said to be in all places; in every living things; literally everywhere. Gurbani tells us, "The Lord Himself is within the self, and outside as well...; the Lord Himself is fully pervading everywhere" and also "You are the Great Giver of all souls; You are the Life within all living beings."
