ŚB 3.1.32

When Akrūra came to Vṛndāvana in search of Kṛṣṇa, he saw the footprints of the Lord on the dust of Nanda-grāma and at once fell on them in ecstasy of transcendental love. This ecstasy is possible for a devotee who is fully absorbed in incessant thoughts of Kṛṣṇa. Such a pure devotee of the Lord is naturally faultless because he is always associated with the supremely pure Personality of Godhead. Constant thought of the Lord is the antiseptic method for keeping oneself free from the infectious contamination of the material qualities. The pure devotee of the Lord is always in company with the Lord by thinking of Him. Yet, in the particular context of time and place, the transcendental emotions take a different turn, and this breaks the mental equilibrium of the devotee. Lord Caitanya displayed the typical example of transcendental ecstasy, as we can understand from the life of this incarnation of God.
