“Ishvara (the Supreme Lord), jiva (the living entity), prakriti (nature), eternal time and karma (activity) are all explained in the Bhagavad-gita. Out of these five, the Lord, the living entities, material nature and time are eternal.” (Shrila Prabhupada, Bhagavad-gita, Introduction)

“Although Prahlada is only five years old, even at this young age he has given up his affectionate relationship with his father and mother. Therefore, he is certainly untrustworthy. Indeed, it is not at all believable that he will behave well toward Vishnu.” (Shrimad Bhagavatam, 7.5.36)

“It is not proper to remain in this place. Let us go to another great forest, as here we have seen numerous calamities which are causes of ruin. The destruction of Putana and the reversal of the cart, and similarly the falling of the trees without the intervention of the wind. Therefore, let us without delay depart from Gokula to Vrindavana, where the earthly calamities will not overpower us.” (Vishnu Purana, 5.6.22-24)

“According to the shastras, there is shreyas and preyas. Shreyas is the ultimate goal. We should act in such a way that ultimately we will become happy. However, if we want immediate happiness and disregard the future, we want preyas. Preyas is for unintelligent people and children. A child enjoys playing all day; he does not want to be sent to school to be educated. Education is shreyas, the ultimate goal. No one is interested in this. The shastras instruct us to aim for shreyas and not be captivated by preyas. The supreme shreyas is bhakti-yoga.” (Shrila Prabhupada, Teachings of Lord Kapila, Vs 43 Purport)

“Although Dhruva Maharaja was only a five-year-old boy, he underwent severe austerities by eating simply dry foliage, drinking only water and taking no food. In this way, after six months, he was able to see the Supreme Personality of Godhead face to face. When he saw the Lord, he forgot all his austerities and said, svamin kritartho'smi: ‘My dear Lord, I am very pleased.’” (Shrila Prabhupada, Shrimad Bhagavatam, 4.30.4 Purport)

“O King, as I repeatedly recall this wondrous and holy dialogue between Krishna and Arjuna, I take pleasure, being thrilled at every moment.” (Sanjaya, Bhagavad-gita, 18.76)

“After hearing all the explanations of all the different meanings of the atmarama verse, Sanatana Gosvami was struck with wonder. He fell down at the lotus feet of Shri Chaitanya Mahaprabhu and began to offer prayers.” (Chaitanya Charitamrita, Madhya, 24.314)

"Considering that it was the appropriate time and seeing a very large crowd at the door, the ocean of compassion, Raghubir, said with a smile, 'Men and women, play happily.' Then all the men and women of the city happily went to play Holi. Seeing Rama’s face, their hearts were full of happiness and attachment that cannot be measured.” (Gitavali, 310.5-6)
