Devotees whose tongues are decorated always with prayers to Lord Krsna are always given respect even by the great saintly persons and sages, and such devotees are actually worshipable by the demigods.
Whoever knows Me as the Supreme Personality of Godhead, without doubting, is the knower of everything. He therefore engages himself in full devotional service to Me, O son of Bharata.
Lord Sri Krsna
When the devotees of Lord Krsna dance, their steps crush the inauspiciousness of the earth, their glances destroy the inauspiciousness of the ten directions, and their raised arms push away the inauspiciousness of the demigods' planets.
By scrutinizingly reviewing all the revealed scriptures and judging them again and again, it is now concluded that Lord Narayana [Krsna] is the Supreme Absolute Truth, and thus He alone should be worshiped.
Skanda Purana, Padma Purana, and Linga Purana
All heads of state should themselves be bona fide representatives of God and should cut down all irreligious systems. Unfortunately they are cowards who declare a secular state. Such a mentality is a way of compromising religious and irreligious systems, but because of this citizens are generally becoming uninterested in spiritual advancement. Thus the situation deteriorates to such an extent that human society becomes hellish.
His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 4.19.26, Purport
Service to Lord Krsna is the original nature of the individual spirit soul. Situated in that service, the individual soul is happy eternally. Rejecting that service, the individual soul becomes attracted to material illusions and suffers the threefold miseries of material life.
Srila Bhaktivinoda Thakura
Sri Datta-kaustubha, Text 29
In this Age of Kali, the holy name of the Lord, the Hare Krsna mantra, is the incarnation of Lord Krsna. Simply by chanting the holy name, one associates with the Lord directly. Anyone who does this is certainly delivered.
