"How wonderful it must be to speak the language of the angels, with no words for hate and a million words for love!"
Angels have existed since the beginning of Creation. They are beings from the lower part of the subtle region of Heaven (Swargaloka). They are the lowest in the hierarchy of positive subtle beings. Their primary purpose is to act as messengers for lower level deities in the lower subtle region of Heaven (Swargaloka). Deities speak in the language of light whereas we humans speak in the language of sound. Angels therefore act as step-down transformers carrying messages from lower level deities to deserving beings in a language they can understand. This is primarily through the medium of putting thoughts in their minds. By deserving beings, we mean humans on Earth and subtle bodies in the Nether region (Bhuvaaloka) who have some background of spiritual practice or merits. The messages are generally about how to address a particular worldly issue. About 5% of times angels themselves also give worldly advice. As their duty is mainly on Earth, most of them are Earthbound. When they are not delivering messages they lead a life devoted to experiencing pleasures in the lower subtle region of Heaven
