You have to set a font which has the required glyphs but you can also 
use different fonts for both scripts and combine them.

\definefallbackfamily [mainface] [ss] [Noto Sans Devanagari]
   [range={devanagari,devanagariextended},
    features=devanagari-two]

\definefontfamily [mainface] [ss] [Noto Sans]

\setupbodyfont[mainface]

\starttext

ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते ।
सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते ॥ ६२ ॥

dhyāyato viṣayān puṁsaḥ
saṅgas teṣūpajāyate
saṅgāt sañjāyate kāmaḥ
kāmāt krodho ’bhijāyate

\stoptext
