" or "तद्भवदिनं"? Let's look at the letters after "तदिति ।": Letter 1: त Letter 2: द् Letter 3: भ (bha)? Wait, let's look at "तद्दिनं": No, between त and दि: There is: 'द्' + 'भ'? Wait, look at line 4: "अथैतद्भूमिकायाऽवगतं" - 'द्भ' looks like 'द्' with 'भ' attached below. In line 26, is it 'द्' with 'भ'? Wait, no: look at "तद्दिनं": Wait, could it be "तद्दिनं"? In line 26: त (ta) द् (d) दि (di) नं (naṃ) Wait, why would there be "तद्भवदिनं"? Wait, look at the letters: "त" then: "द्" with "दि" = "द्दि"? Wait, in Devanagari, 'द्दि' is 'द' with another 'द' below, and 'ि' matra! Let's look at it: It's 'त' + 'द्दि' + 'नं' = "तद्दिनं"! Wait, is there a 'भ'? No! Look: it's त् + दि = त्दि or द् + दि = द्दि
