# SB 3.11.42 > तदाहुरक्षरं ब्रह्म सर्वकारणकारणम् । > विष्णोर्धाम परं साक्षात्पुरुषस्य महात्मनः ॥४२॥ ## Text > tad āhur akṣaraṁ brahma > sarva-kāraṇa-kāraṇam > viṣṇor dhāma paraṁ sākṣāt > puruṣasya mahātmanaḥ ## Synonyms *tat*—that; *āhuḥ*—is said; *akṣaram*—infallible; *brahma*—the supreme; *sarva*-*kāraṇa*—all causes; *kāraṇam*—the supreme cause; *viṣṇoḥ* *dhāma*—the spiritual abode of Viṣṇu; *param*—the supreme; *sākṣāt*—without doubt; *puruṣasya*—of the *puruṣa* incarnation; *mahātmanaḥ*—of the Mahā-Viṣṇu. ## Translation **The Supreme Personality of Godhead, Śrī Kṛṣṇa, is therefore said to be the original cause of all causes. Thus the spiritual abode of Viṣṇu is eternal without a doubt, and it is also the abode of Mahā-Viṣṇu, the origin of all manifestations.** ## Purport Lord Mahā-Viṣṇu, who is resting in *yoga-nidrā* on the Causal Ocean and creating innumerable universes by His breathing process, only temporarily appears in the *mahat-tattva* for the temporary manifestation of the material worlds. He is a plenary portion of Lord Śrī Kṛṣṇa, and thus although He is nondifferent from Lord Kṛṣṇa, His formal appearance in the material world as an incarnation is temporary. The original form of the Personality of Godhead is actually the *svarūpa,* or real form, and He eternally resides in the Vaikuṇṭha world (Viṣṇuloka). The word *mahātmanaḥ* is used here to indicate Mahā-Viṣṇu, and His real manifestation is Lord Kṛṣṇa, who is called *parama,* as confirmed in the *Brahma-saṁhitā:* > īśvaraḥ paramaḥ kṛṣṇaḥ > sac-cid-ānanda-vigrahaḥ > anādir ādir govindaḥ > sarva-kāraṇa-kāraṇam > [Bs. 5.1] "The Supreme Lord is Kṛṣṇa, the original Personality of Godhead known as Govinda. His form is eternal, full of bliss and knowledge, and He is the original cause of all causes." Thus end the Bhaktivedanta purports of the Third Canto, Eleventh Chapter, of the *Śrīmad-Bhāgavatam,* entitled "Calculation of Time, From the Atom."
