Bhagavad Gita -Sri Madhvacharya
(Bhashya and Tatparya Nirnaya)
Those who have no concentration, for them there is no wisdom. Hence the scriptures  say 'one who is not tranquil, one who has not concentrated'. It is said that the Resplendent Lord is exceedingly pleased with those who are ascetics. In Narayana Shatakshara Kalpa it is said that among all the initiations, the one which is made in stage of asceticism is the supreme and extremely pleasing to Me. Even among the qualified, only the householders who have concentrated mind become primarily eligible. The Resplendent Lord is highly pleased with them. The Gods and many well known princes, even though were ever engaged in actions, did not have their minds wavering from Sri Vishnu. Therefore even when they were engaged in pleasures, Sri Vishnu was pleased, thus, in Padma Puraana.
