कृष्णकृत्यानि कंसस्य देवक्या: कुर्वते भयम् ।

मातुस्ते व्याकुलीभाव: चक्रे ते कृष्णतां तनौ ।।३३२।।

The dark deeds of your uncle Kaṃsa cause fear in your mother, Devakī.  The scare of your mother, O Kr̥ṣṇa, caused the dark hue of your body.

अथवा सञ्चितं पापं भक्तानां यदपाकृतम् ।

कुरुते कृष्णरूपं ते कण्ठे शम्भोर्विषं यथा ।। ३३३।।

Perhaps it is the accumulated sins of your devotees that you removed that is causing your dark hue, like the [held up] poison in the throat of Śiva.

यदा सा जानकी वह्नौ प्रविष्टा शुद्धिदर्शने ।

दाहभीत्या व्याकुलस्त्वं तत् स्मृत्वा कृष्णतां गत: ।।३३४।।

When Sītā entered the fire to show her purity, you were worried of her burning.  Remembering that you developed a dark hue.

वराहरूपं धृत्वा त्वं धृतवान् धरणीं जले ।

उदिते दन्तशिखरे, धरा ते कृष्णतां ददौ ।।३३५।।

Assuming the form of a boar when you held high on your raised tusk the earth in the water, that earth gave you your dark hue.

अतिक्रान्तो वसुमतीं वामनस्त्वं त्रिविक्रम: ।

तदा तत्स्पर्शयोगेन वपुस्ते कृष्णतामयात् ।।३३६।।

When you traversed the earth assuming the form of a dwarf taking three steps, then by the touch of that earth your body became dark.

नृसिंहरूपं धृत्वा त्वं यदोदरमदारय: ।

हिरण्यकशिपो: कृष्ण, क्रोध: कृष्णत्वकारणम् ।।३३७।।

Assuming the form of Man-Lion, when you tore apart the belly of the demon Hiraṇyakaśipu, your anger became the cause of your dark hue.

तेज: सहस्रसूर्याणां भक्तनेत्रेऽतिदाहकम् ।

इति चिन्ताकुल: कृष्ण स्वयं कृष्णत्वमागत: ।।३३८।।

The brilliance of a thousand suns will be too scorching for the eyes of the devotees.  With this worry, O Kr̥ṣṇa, you assumed a dark hue.

यथाकथञ्चित् कृष्णत्वं कृष्ण ते समजायत ।

मा चिन्तां कुरु गोविन्द यथासि त्वं प्रियोऽसि मे ।।३३९।।

Whichever way your dark hue came about, O Kr̥ṣṇa, do not worry.  I love you as you are.

कीदृश: कृष्ण रागस्ते रोगो वायं जनार्दन ।

स्मृतमात्रोऽपि गोविन्द प्रसृतोऽस्यभितो हरे ।।३४०।।

What kind of a hue or an illness you are, O Kr̥ṣṇa.  Merely by remembering you, O Govinda, you have spread around me.
