SB 3.29.21

Purified consciousness or Krsna consciousness means to see everywhere presence of Krsna. Therefore, if one is engaged only in the Deity worship in the temple and does not take care of other living entities, then he is considered in the lowest grade of devotional service. One who worships the Deity in the temple and does not show respect to others, he is called a devotee in the material platform or in the lowest stage of devotional service. So a devotee should try to understand everything in relationship with Krsna and try to serve everything in that spirit. To serve everything means to engage everything in the service of Krsna. Supposing a person is innocent, he does not know what is his relationship with Krsna. A devotee who is advanced, he should try to engage him also in the service of Krsna. Not only living being, but everything can be engaged in the service of Krsna if one has advanced in Krsna consciousness.
