Significance of Devotional Service
Without devotional service, all other methods for spiritual self-realization are weak and insignificant. Unless one comes to the devotional service of Lord Krishna, jnana yoga cannot give the desired results.
Intelligence And Energy of The Supreme Personality of Godhead
Nondevotees factually appreciate the wonderful creation of material nature, but they cannot appreciate the intelligence and energy of the Supreme Personality of Godhead, who is behind this material creation.
Sri Chaitanya Caritamrta,
Adi Lila 7.121
A Transcendental Joy For The Lord
He is the father of everyone but when His devotee takes it for granted that the Lord is to be protected by the devotee’s care, it is a transcendental joy for the Lord.
Srimad Bhagavatam 3.2.26,
Srila Prabhupada
Consciousness
Consciousness is originally pure, like water. But if we mix water with a certain color, it changes. Similarly, consciousness is pure, for the spirit soul is pure. But consciousness is changed according to the association of the material qualities.
Bhagavad-gita 15.9,
Srila Prabhupada
