Bhakthi can be spoken of as having several stages

Bhakthi can be spoken of as having several stages. Mukhyabhakthi is the stage where the Seva (service) of the Lord alone matters and it is its own reward; the devotee does not seek anything more than just the service of the highest, done to the utmost of capacity. This gradually becomes Paraabhakthi, where nothing except the Name and Form of the Beloved is cognized. Again, there is what is called Gounabhakthi, which is colored by the three Gunas (inner qualities): the attitude of the Aartha (the afflicted), the Arthaarthi (the seeker of worldly comfort), the Jijnaasu (the sincere inquirer) and the Jnaani (the wise man) who is silent and content with the realization that all is He. - Bhagavan sri sathya sai Baba, Source: Sathya Sai Speaks 01 - 1953-60.
