andha tamasa

 The standard Devanagari spelling is अन्ध तमस, though in Sanskrit the compound form अन्धतमस is also common depending on context.

Short answer (bolded for quick reference):

• Separated phrase: अन्ध तमस
• Compound (common in Sanskrit texts): अन्धतमस

What the transliteration “andha tamasa” represents

The phrase can correspond to two related Sanskrit constructions:

• andha (अन्ध) — “blind,” “dark,” or “obscured.”
• tamas / tamasa (तमस् / तमस)— “darkness,” “ignorance,” or “gloom.”
  • In a sentence, tamasa (तमसा / तमसः / तमसम्) may appear in different case endings, but the stem is tamas (तमस्).

Because transliteration often omits case endings and sandhi, “andha tamasa” can be interpreted either as two separate words or as a compound.

1. Separated form: “andha tamasa” → अन्ध तमस

If the user intends the basic lexical form (dictionary headwords), the standard Devanagari spellings are:

• andha → अन्ध
• tamas → तमस

Together: अन्ध तमस

This is the most neutral, “uninflected” representation.

2. Compound form: “andhatamasa” → अन्धतमस

In classical Sanskrit, the idea of “blind darkness,” “utter darkness,” or “deep ignorance” is often expressed as a tatpuruṣa compound:

• andhatamas / andhatamasa → अन्धतमस

This compound appears in philosophical and scriptural contexts (e.g., discussions of ignorance, darkness, or lower realms).
It is a single word, not two.

3. Case‑inflected forms (if “tamasa” is meant literally)

If the user’s transliteration “tamasa” is meant as a case form, the spelling changes:

• तमसा (tamasā) — instrumental singular (“by darkness”)
• तमसः (tamasaḥ) — genitive singular (“of darkness”)
• तमसम् (tamasam) — accusative singular (“darkness” as object)

But since the question asks for the standard spelling, the dictionary form तमस is the correct base.

Which form should you use?

Use अन्ध तमस if you want the two separate dictionary words.
Use अन्धतमस if you want the classical compound meaning “blind darkness” or “deep darkness.”
