A living being in his normal constitutional position is fully satisfied in spiritual bliss. This state of existence is called brahma-bhūta (SB 4.30.20) or ātmā-nandī, or the state of self-satisfaction. This self-satisfaction is not like the satisfaction of the inactive fool. The inactive fool is in the state of foolish ignorance, whereas the self-satisfied ātmānandī is transcendental to the material state of existence. This stage of perfection is attained as soon as one is fixed in irrevocable devotional service. Devotional service is not inactivity, but the unalloyed activity of the soul.
The soul's activity becomes adulterated in contact with matter, and as such the diseased activities are expressed in the form of lust, desire, hankering, inactivity, foolishness and sleep. The effect of devotional service becomes manifest by complete elimination of these effects of passion and ignorance. The devotee is fixed at once in the mode of goodness, and he makes further progress to rise to the position of Vāsudeva, or the state of unmixed sattva, or śuddha-sattva. Only in this śuddha-sattva state can one always see Kṛṣṇa eye to eye by dint of pure affection for the Lord.
A devotee is always in the mode of unalloyed goodness; therefore he harms no one. But the nondevotee, however educated he may be, is always harmful. A devotee is neither foolish nor passionate. The harmful, foolish and passionate cannot be devotees of the Lord, however they may advertise themselves as devotees by outward dress. A devotee is always qualified with all the good qualities of God. Quantitatively such qualifications may be different, but qualitatively both the Lord and His devotee are one and the same.
