We should always keep Krsna within our minds, for Krsna is like the sun. This is the motto of our Back to Godhead magazine: Krsna is just like the brilliant sun, and maya, ignorance, is just like darkness. When the sun is present, there cannot be darkness. So if we keep ourselves in Krsna consciousness always, we cannot be influenced by the darkness of ignorance; rather, we shall always walk very freely in the bright sunshine of Krsna.

Teachings of Queen Kunti, p. 163-164

Even the entirety of whatever there may be within the three worlds to satisfy one's senses cannot satisfy a person whose senses are uncontrolled.

– Lord Vamanadeva, Srimad-Bhagavatam 8.19.21

There is nothing more sinful than untruthfulness. Because of this, Mother Earth once said, "I can bear any heavy thing except a person who is a liar."

– Bali Maharaja, Srimad-Bhagavatam 8.20.4

The prayers of the impersonalists offend the Lord more than denunciation by His avowed enemies.

– Srila Bhaktisiddhanta Sarasvati Thakura,
Real and Apparent (Divine Form)

I desire to be in Vrndavana so that I may sit on the bank of the Yamuna and pass each long day of my life in the twinkling of an eye, meditating on Lord Krsna.

– Adi Sankaracarya, Abhilasastaka

There is no friend equal to knowledge. There is no enemy equal to disease. There is no affection equal to that received from one's own child. And there is no strength superior to the will of God.

– Canakya Paniita

Of secret things I am silence.

– Lord Krsna, Bhagavad-gita 10.38

The person who has not at any time received the dust of the feet of the Lord's pure devotee upon his head is certainly a dead body. And the person who has never experienced the aroma of the tulasi leaves from the lotus feet of the Lord is also a dead body, although breathing.

– Saunaka Rsi, Srimad-Bhagavatam 2.3.23

Give up the shackles of matter slowly. Cultivate your spirit inwards. Give up prejudices which you have acquired from the so-called rational thinkers who deny the existence of spirit. Be humble in your self and learn to respect those who work towards spiritual attainments. Do these with your heart, mind, and strength in the company of spiritual people alone, and you will see Krsna in no time.

– Srila Bhaktivinoda Thakura,
Shree Chaitanya Mahaprabhu, His Life and Precepts

There is no stronger obstruction to one's self-interest than thinking other subject matters to be more pleasing than one's self-realization.

– Sanat Kumara, Srimad-Bhagavatam 4.22.32
