Attitude
Temple atmosphere should be a pure Vaishnava atmosphere. Our attitude should be how can I serve you? What can I do for you? And you will see how people will respond.
Scriptures
Study of scriptures will not give us love of God, only mercy can but yes, study of scriptures teaches us how to get that mercy.
Devotion With Concentration
There may be many excellent techniques to concentrate better while chanting the Lord’s holy names, all of which are very, very good. However God is not pleased just by concentration. He is pleased by devotion. That means the character of our life.
Spirituality
When we become connected to the supreme spirit then we automatically becomes situated in our spiritual identity.
