“Anarthas, unwanted things, come down from one bodily life to another. To get out of this entanglement, one has to take to the devotional service of Lord Vasudeva, Krishna, the Supreme Personality of Godhead. The word guru is significant in this connection. The word guru may be translated as ‘heavy,’ or ‘the supreme.’ In other words, the guru is the spiritual master.” (Shrila Prabhupada, Shrimad Bhagavatam, 4.29.36-37 Purport)
