PURPORT
We should note with profit that in the first three chapters of the Second Canto, a gradual process of development of devotional service is being presented. In the First Chapter the first step in devotional service for God consciousness by the process of hearing and chanting has been stressed, and a gross conception of the Personality of Godhead in His universal form for the beginners is recommended. By such a gross conception of God through the material manifestations of His energy, one is enabled to spiritualize the mind and the senses and gradually concentrate the mind upon Lord Viṣṇu, the Supreme, who is present as the Supersoul in every heart and everywhere, in every atom of the material universe. The system of  pañca-upāsanā , recommending five mental attitudes for the common man, is also enacted for this purpose, namely gradual development, worship of the superior that may be in the form of fire, electricity, the sun, the mass of living being, Lord Śiva and at last, the impersonal Supersoul, the partial representation of Lord Viṣṇu.
