SB 11.20.34

The words ekāntino mama indicate that the pure devotees of the Lord, being saintly and most intelligent, dedicate themselves exclusively to the devotional service of the Personality of Godhead. Even when the Lord offers them personal liberation from birth and death, the devotees will not accept it. A pure devotee automatically gains an eternal life of bliss and knowledge in the Lord’s personal abode and thus considers mere liberation without the loving service of the Lord to be most abominable. One who chants Lord Kṛṣṇa’s holy name or superficially serves the Lord with the motive of achieving impersonal liberation or material sense gratification cannot be considered a transcendental devotee of the Lord. As long as one desires mundane religiosity, economic development, sense gratification or liberation, one cannot achieve the platform of samādhi, or perfect self-realization. Every living entity is actually the eternal servant of Lord Kṛṣṇa and is constitutionally meant to engage in the loving service of the Lord without personal desire. This pure and supreme status of life is described in this verse by the Lord Himself.
