Coveted objects like wealth, fame, and material enjoyment make one forget Krishna. As a result, misfortune and inauspiciousness arise. Only devotional service is the reservoir of all auspiciousness.- Srila Bhaktisiddhanta Sarasvati Thakura Sri Caitanya-bhagavata, Antya-khanda 9.114, Commentary
There are no religious principles other than Vaishnava dharma. All other religious principles that have been or will be preached are either supportive or distorted forms of Vaishnava dharma. Whenever they manifest as supportive, one should respect them. Whenever they appear to distort Vaishnava dharma, one should cultivate one’s own devotional service without being envious. – Srila Bhaktivinoda Thakura Jaiva Dharma, Chapter 8
Krishna is the original Supreme Personality of Godhead the perfect and complete supreme master, who stays above the material energy. We demigods, who are parts of the parts of His incarnations, create this world with the aid of His potencies.- Lord Brahma Sri Garga-samhita 2.9.2
I am never manifest to the foolish and unintelligent. For them I am covered by My internal potency, and therefore they do not know that I am unborn and infallible.- Lord Sri Krishna Bhagavad-gita 7.25
Self-controlled persons are able to see the Supreme Personality of Godhead, who cannot be seen by material eyes or understood by the material mind, who has no material family, no material caste, and no material eyes, ears, hands, or feet, who is eternal, all-powerful, all-pervading, subtle, and unchanging, and who is the creator of all.- Mundaka Upanisad 1.1.5–6
O Narada, I, along with Parvati, Kartikeya, and Ganesa, always chant the Lord’s holy names. I do not consider a cloudy day to be a bad day. The day that passes without discussions of Lord Krishna is actually a bad day.- Lord Siva Sri Narada-pancaratra 2.2.25
