The one Supreme Lord lives hidden inside all created things. He pervades all matter and sits within the hearts of all living beings. As the indwelling Supersoul, He supervises their material activities. Thus, while having no material qualities Himself, He is the unique witness and giver of consciousness. – Svetasvatara Upanisad (6.11)
My Lord, please free me, Your partial expansion, from the bondage created by Your maya. Please do this, O abode of supreme bliss, by directing me to the service of Your feet. – Srila Sridhara Svami, Commentary on Srimad-Bhagavatam (10.87.21)
Understand this essential fact of life: life is temporary and full of all kinds of miseries. So take shelter of the holy name as your only business. – Srila Bhaktivinoda Thakura, Arunodaya-kirtana (1.6)
As soon as one becomes inimical to Krsna and desires sense gratification, he is immediately struck down by the illusory energy of the Lord.- Srila Jagadananda Pandita, Prema Vivarta 2 
Lord Krsna, the original Supreme Personality of Godhead, sometimes descends to the world of men with His associates and transcendental abode. He removes the burden of the earth and delights His devotees. – Srila Visvanatha Cakravarti Thakura, Aisvarya-Kadambini (2.6)
