aksharanam a-karo ’smi
dvandvah samasikasya ca
aham evakshayah kalo
dhataham vishvato-mukhah

"Of letters I am the letter A, and among compound words I am the dual compound. I am also inexhaustible time, and of creators I am Brahma."

Another Four groups are mentioned. Aksharanam = among alphabets or syllables, akara = alphabet or syllable 'a' [அ or अ ]. Samasikasya = among compound words, dvandva = dvandham. Aham = I [Sri Krishna] am, akshaya = never ending, kala = time, vishvato-mukha = four faced, dhata = Brahma. In Thirukkural [திருக் குறள்], the first kural is akara mudhala ezhuthellam... [அகர முதல எழுத்தெல்லாம்.. ]. Just like the Lord is the cause for all Universe, letter 'a' is for all letters. From this letter all sounds are emanating. Vedas say that the Lord resides in the beginning and end of chanting of Vedas, pranavam - AUM [ஓம் or ॐ ]. In pranava, the first letter is 'a'. All letters and syllables will merge in pranavam and pranavam merges in 'a'. Akarartho vishnu: - the letter 'a' is Sri Vishnu. 'A' in Sanskrit is a root syllable. If someone is denoted with syllable 'a', he is the protector. Since the Lord protects all at all times, 'a' denotes Him. Samasam means the joining of two words. When letters join it is called sandhi; for joining words it is samasam. There are Four types of samasam:

  • Advayi bhava samasam - upa-ganga means the shore of river ganga. Upa indicates near and ganga means the river. In this junction, upa gets the importance as we talk about the shore. First word gets the prominence.
  • Tatpurusha samasam - Raja-purusha means the servant of the King. Here the prominance is for the employee or servant and not the King. The latter word is important here.
  • Bahivridi samasam - Here, the joining of the words will be given importance. In pithambaram, which means yellow [pitham] cloth [ambaram], neither of the two words get importance but a third word pithambaram gets importance.
  • Dwandha samasam - Both the words get importance as in Rama-Lakshmanau. Both Rama and Lakshmana get importance.
In this Kshetram also both Swami Nathamuni and Swami Alavandar are given importance. Time can never end and it goes on for ever. Dhata denotes lord Brahma and he sees everywhere with his four faces.
