4. The red colour of lightning is from fire, the white colour is from water, and the dark colour is from earth. Thus that which constitutes the ‘lightning’-ness of lightning is gone. All changes are mere words, in name only. The three colours are the reality.
Yat vidyutaḥ rohitam rūpam, that red colour of lightning; tat rūpam tejasaḥ, that colour is from fire; yat śuklam, that which is white; tat apām, that is from water; yat kṛṣṇam, that which is dark; tat annasya, that is from earth [lit., food]; vidyutaḥ vidyuttvam apāgāt, [thus] the ‘lightning’-ness of lightning is gone; vācārambhaṇam nāmadheyam vikāraḥ, all changes are mere words, in name only; trīṇi rūpāṇi iti eva satyam, only the three colours are the reality [i.e., outside of the three colours, there is no lightning].
