स्नपयतु · क्रिया — let him bathe; the causative of √स्ना with णिच्, ‘make to bathe’, so the cloud gives Skanda a ritual bath, अभिषिञ्चतु, and the imperative is the request
भवान् · कर्ता — your honour, the polite ‘you’; the subject of the third-person imperative, and Mallinātha adds स्वयमेव, ‘you yourself’, since the cloud is to send no one
पुष्पमेघीकृतात्मा · बहुव्रीहि agreeing with भवान् — having made your own body a cloud of flowers, पुष्पमेघीकृतविग्रहः, possible कामरूपत्वात्, because the cloud can take any shape
स्कन्दम् · कर्म — Skanda, कुमारं स्वामिनम्, the Boy and the Lord; the god the cloud is to bathe

पुष्पासारैः · करण / तृतीया — with showers of flowers, पुष्पसम्पातैः; the instrument of the bathing, and आसार is a hard downpour, धारासम्पातः, not a sprinkling
व्योमगङ्गाजलार्द्रैः · agreeing with पुष्पासारैः — wet with the water of the sky-Ganges, so the flower-shower is a real shower and the bathing a bathing
तत्र · क्रियाविशेषण / अधिकरण — there, देवगिरौ, on Devagiri; the place named in the stanza before, carried over in one word
तेजः · the ground of the command — for that fiery power of his; the last half is a second, verbless sentence justifying the worship, hung here under the verb it explains
हि · for — the particle of a reason given, making the last half the reason for the first; अतः पूज्यमिति भावः, ‘therefore it is worthy of worship’
तत् · that — the pronoun pointing at Skanda, neuter by विधेयप्राधान्यात् though he is masculine; ‘that light is what he is’
अत्यादित्यम् · agreeing with तेजः — brighter than the sun, आदित्यमतिक्रान्तम्, an अति-compound naming what it surpasses
संभृतम् · agreeing with तेजः — gathered, सञ्चितम्; the passive क्त, its agent the instrumental नवशशिभृता
हुतवहमुखे · अधिकरण — in the mouth of fire, हुतवहस्य मुखे; the mouth named to signal purity, शुद्धत्वसूचनार्थम्
नवशशिभृता · करण / कर्तरि तृतीया — by him who wears the new moon, चन्द्रशेखरेण, Śiva; the agent who gathered the fire
रक्षाहेतोः · हेतु — for the sake of protection, रक्षार्थम्; the हेतु-compound that licenses the genitive below
चमूनाम् · षष्ठी हेतुप्रयोगे — of the armies, सेनानाम्; the genitive of cause licensed by the word हेतु
