The way to serve guru can be through vapu or through vani. For vapu service, one has to be in proximity of the guru. That may not be possible at all times, for all disciples. The other way to serve guru is through vani – by hearing the instructions of the guru and imbibing in one’s life.
One of the ways of devotion is that one should always feel satisfied on the material plane and always be dissatisfied on the spiritual plane. Therefore, if one has a desire to serve the spiritual master, it is good. Genuine desire is always rewarded by the spiritual master with some service.
