To realise the Lord in every being, you must cultivate prema and drive out the bats that infest the dark caverns of your heart; the bats of hate, envy and malice. Let the light of prema illumine your thoughts, your words, your movements, your activities, your judgements. When you become transmuted into prema, the Lord, who is Prema swarupa will reveal Himself to you and play on the flute, awakening your higher consciousness in a flood of universal love. (SSS Vol.4, p. 95)
Unless one gets rid of sloth and slumber
One cannot find truth;
Unless one is free from passionate activity
One cannot attain devotion
It is only through Sattva guna
One can attain devotion
This is the truth being revealed. (Telugu Poem)
