Please accept my humble obeisance. All glories to Srila Prabhupada
The mahatma is always engaged in different activities of devotional service, as described in the Srimad-Bhagavatam, hearing and chanting about Visnu, not a demigod or human being. That is devotion: sravannam kirtanam visnoh and smaranam, remembering Him. Such a mahatma has firm determination to achieve at the ultimate end the association of the Supreme Lord in any one of the five transcendental rasas. To achieve that success, he engages all activities — mental, bodily and vocal, everything — in the service of the Supreme Lord, Sri Krsna. That is called full Krsna consciousness.
