Devotee
The symptom of a Vaishnava is trinad api sunicena taror api sahisnuna, that's the perfect definition of a Vaishnava. Another consideration is that a Vaishnava is a surrendered soul to Krishna.
Consciousness
Krishna Consciousness means being conscious of Krishna's mercy at every single moment.
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.
Spirituality
When we become connected to the supreme spirit then we automatically becomes situated in our spiritual identity.
