“In the middle of the day, it is exceedingly pleasant to go about and it is delightful to the touch. In the daytime the sun is pleasing, while the shade and water are not pleasing.” (Lakshmana speaking to Lord Rama, Valmiki Ramayana, Aranya Kand, 16.10)

“This knowledge is the king of education, the most secret of all secrets. It is the purest knowledge, and because it gives direct perception of the self by realization, it is the perfection of religion. It is everlasting, and it is joyfully performed.” (Lord Krishna, Bhagavad-gita, 9.2)
