Love of God
All worship is towards cleansing our mind and for our own progress; there is nothing that the Lord gains.

Is there water that God has not seen? Ganges herself resides in Siva’s tresses. Where is the question of our performing abhishekam? Did we create Vibhuthi (holy ash)? God created the cow for producing milk, we dry its dung, burn it, and from that ash, we create Vibhuthi and offer it to the Lord. There is no single thing in this world that is alien to God. All worship is towards cleansing our mind and for our own progress; there is nothing that the Lord gains.
Even if you do not offer worship, God will continue doing good for you. This is because God is a concept that is more loving and superior to the compassion of a mother.
A true guru inspires people to learn from his life that is his message.
