Auspicious
मङ्गळmaṅgaḻaMaṅgaḻa, and its near word śubha, is what brings good and turns harm away. The hymn names the Lord the Supreme Auspiciousness, the highest good and the highest giver of it, and Bhīṣma's first verses already speak of Him as the auspiciousness of all that is auspicious. So for the devotees of Vāsudēva nothing inauspicious is to be found anywhere.
The word spreads through many names. He is Śiva, the Auspicious One, for the word means good and kindly and spotless; the teachers read the name as the One who brings auspiciousness, and find it used of Him in the Nārāyaṇa Upaniṣad. He is Śubhēkṣaṇa, whose glance brings only good; Śubhāṅga, of auspicious limbs, from the crown to the lotus feet; and Śrēyaḥ Śrīmān, the highest good, full of Śrī.
Why the Lord is called auspicious is told in the Viṣṇu Purāṇa's words: the Supreme is known as the good because remembering Him alone wards off evil and brings a long train of blessings. The tradition adds that nothing He touches stays unblessed: a garland, a jewel or a flower laid at His feet is made fortunate by the touch.
