Of Lights I am the radiant Sun.
Bhagavad Gita 10.21,
Of sacriﬁces I am the chanting of the holy names [japa].
Bhagavat Gita 10.25
O son of Kunti, the nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons. They arise from sense perception, O scion of Bharata, and one must learn to tolerate them without being disturbed.
Bhagavad Gita 2.14,
