The lines with “uLan kaNDAi nannenjE” can be found at several places in the Iyar Pa. This is one remarkable occurrence. “uLan kaNDAi nannenjE uttamanenRum uLan kaNDAi uLLuvAruLLattu uLankaNDAi” – Perumal resides in the heart of those who think of Him. Only when there is a thought of Perumal, one can know whether He is in one’s heart. Whoever thinks of Perumal, He certainly is in their minds; ask such people and you will know. Those who do not think of Perumal, will look for Him externally. For those who think about Him, He is in their heart and mind forever.
Similarly, “veLLattinuLLAnum vEnkatattumEyAnum” – He is everywhere externally and internally in our hearts. Bhagavan is in many states such as Vibhavam, ArchA, Antaryami, etc., only to grace us many ways. As an Antaryami, He is in our hearts; in the Vibhava state, He incarnates; in the ArchA form, He is present as Idols. When Bhagavan is thus present in many forms, how can one say that He does not exist? These pasuram-s basically make us realize that He is in many forms.
