Explanation of the  Atmarama  Verse in  Srimad Bhagwatam

engaged in His devotional service. The nine mystics mentioned in the Eleventh Canto of  Srimad Bhagwatam  are understood to have been transcendentalists from birth by hearing the transcendental qualities of Krishna from Brahma and Lord Shiva and Narada.
Sometimes one becomes attracted to Krishna and His transcendental qualities simply by looking upon the beautiful features of His transcendental Body, and in that case also one gives up the desire for liberation and becomes engaged in the devotional service of the Lord. The devotee repents his loss of time in the so-called cultivation of knowledge, and becomes a pure devotee of the Lord.
There are two kinds of liberated souls even in this material body: the soul liberated by devotional service, and the soul liberated by the cultivation of knowledge. The difference is that the liberated soul in devotional service becomes more and more elevated, being attracted by the transcendental qualities of Krishna, whereas the dry speculators who simply cultivate knowledge without any connection with devotional service become fallen on account of their many offences.
This is confirmed in the  Srimad Bhagwatam , Tenth Canto, Second Chapter. It is said there, "O my Lord, the intelligence of those who think themselves liberated without a touch of devotional service is not pure, because, even though they rise to the highest point of liberation by severe penances and austerity, still, with no center at Your Lotus Feet, they are sure to fall down again into this material existence."  Bhagavad Gita  also confirms this, in the Eighteenth Chapter, 54th verse—one who is actually situated in the  Brahman  realization has nothing to lament for and nothing to desire. He is equipoised toward everyone, and thus is eligible for being situated in devotional service.
This same thing is accepted by Bilvamongal Thakur. In his later life, he lamented that, "I was situated as a monist, to become One with the Supreme Lord, but somehow or other, I contacted a Naughty Boy, and I became His eternal servitor." In other words, those who become self-realized souls by executing devotional service can achieve a transcendental body, and by being attracted to the transcendental qualities of Krishna, they become engaged fully in pure devotional service.
Anyone who is not attracted to Krishna is understood to be still under the spell of Maya. Therefore, one who is trying to be liberated by devotional service is actually liberated from the spell of Maya. In the Eleventh Canto of  Srimad Bhagwatam  there are many instances of devotees who became liberated in this life simply by their engagement in devotional service.
