Sri Krishna Janmastami

The appearance day of Lord Krishna, who the Vedic scriptures describe as the Supreme Lord, in this material world is celebrated as Janmastami.

yadā yadā hi dharmasya
glānir bhavati bhārata
abhyutthānam adharmasya
tadātmānaṁ sṛjāmy aham

TRANSLATION
Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion—at that time I descend Myself.
(Bhagavad-gita 4.7)

paritrāṇāya sādhūnāṁ
vināśāya ca duṣkṛtām
dharma-saṁsthāpanārthāya
sambhavāmi yuge yuge

TRANSLATION
To deliver the pious and to annihilate the miscreants, as well as to reestablish the principles of religion, I Myself appear, millennium after millennium.
(Bhagavad-gita 4.8)

janma karma ca me divyam
evaṁ yo vetti tattvataḥ
tyaktvā dehaṁ punar janma
naiti mām eti so ‘rjuna

TRANSLATION
One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.
(Bhagavad-gita 4.9)

So Kṛṣṇa also becomes very beautiful. He’s already beautiful, but when a devotee serves Him, a devotee comes to Him, He also becomes very beautiful. A devotee, when with his heart and soul, serves Kṛṣṇa in dressing Him, in feeding Him, in giving Him flower, He becomes smiling. And if you can get Kṛṣṇa once smiling upon you, your life is fulfilled.
