"Antaryamin means the one who can observe & know every thing of your heart without you being explaining anything to Him. So God is called Antaryamin as we need not explain to Him about any of our problems. In this aspect He is Antaryamin & He knows what we want."
So God is seated in all beings as the Antaryamin. God is also everywhere as the Omnipresent God (Sarva-vyapi Bhagavan). In Bhagwat Gita: Chapter Thirteen, Lord Krishna explains about the Body & the Soul. As per that this body is the field, and the Being (Soul) who is seated in this field is called the Knower of the field. Lord Krishna says, "O Arjuna, know Me to be the Knower of the field in all the fields i.e. I am the Soul present in all the bodies". In all other creatures & animals also, Lord is there in their bodies as Antaryamin God. God is the beginning, the middle and the end of all creatures.
Below are few verses of Bhagwat Gita explaining that God is the Spiritual Reality (Soul) in all the creatures:
"kshetra-jnam chapi mam viddhi
yat taj jnanam matam mama" (Bhagwat Gita: Chapter Thirteen verse 3)
"Sri Krishna said: O Arjuna, you should understand that I am also the knower (Soul) in all the bodies, and to understand this body and its knower (Soul) is called knowledge. That is My opinion."
"bahir antas cha bhutanam
acharam charam eva cha
suksmatvat tad avijneyam
dura-stham chantike cha tat" (Bhagwat Gita: Chapter Thirteen verse 16)
"Sri Krishna said: O Arjuna, The Supreme Truth (Super Soul) exists outside and inside of all living beings, the moving and the nonmoving. Because He is subtle, He is beyond the power of the material senses to see or to know. Although far, far away, He is also near to all."
"avibhaktam cha bhutesu
vibhaktam iva cha sthitam
bhuta-bhartr cha taj jneyam
grasisnu prabhavishnu cha" (Bhagwat Gita: Chapter Thirteen verse 17)
"Sri Krishna said: O Arjuna, Although the Supersoul appears to be divided among all beings, He is never divided. He is situated as one. Although He is the maintainer of every living entity, it is to be understood that He devours and develops all."
"aham atma gudakesha
aham adis cha madhyam cha
bhutanam anta eva cha" (Bhagwat Gita: Chapter Ten verse 20)
"Sri Krishna said: I am the Super Soul, O Arjuna, seated in the hearts of all living entities. I am the beginning, the middle and the end of all beings."
So as God is there in your heart in "Antaryamin" aspect, you can always find some time from your daily routine & can pray to Him while closing your eyes. Daily praying to Him like this shall make you more peaceful & shall make you feel more closer to God. A deer who is having the Kasturi (Musk) in his body only, searches for the cause of fragrance all over there in the wild, while that sweet fragrance comes from the inside of his body only. Same is the case with us that we are searching for the God outside ourselves while He is sitting in our heart only.
Jai Sri Krishna
