In plain words
Make firm in your mind, again and again, the feeling that He is everywhere.
God Is Everywhere
So the Bhagavad Gītā said, ‘Sarvataḥ pāṇipādaṃ, tatsarvatokṣi śiromukhaṃ, sarvataḥ śrutimalloke, sarvamāvṛtya tiṣṭhati.’ Yadbhāvaṃ tadbhavati. O God! Why should You not be behind me, beside me, in my home and before my eyes, and protect me? Then, at one time, God gave the answer. Devotee! I am always right with you. I am right behind you. I am right within you. So do not try to search for Me in some place outside. O God! Are You really right behind me? ‘Certainly; your body is My very shadow,’ He said. Is this true! Are You right behind me? So he turned round and looked; He was not to be seen. O God! You, speaking Asatya! You said You were right behind me. But when I turn, You are not behind me! Foolish one! When you turned, your back turned too, did it not! Right behind your back, I too had to turn. So, not grasping this truth, you take ‘behind me’ to mean there is some chair, and you are looking at it. When you bend like this, there is the chair behind you. When it is at your side, your chair comes right to your side. That is why ‘sarvataḥ pāṇi pādaṃ’: God is there to fit the feelings with which each one prays, in whatever way he prays.
‘O God! Have You no ears to hear my prayer? Why do You not hear my prayer? Why does my prayer not fall into Your ear?’ For those who pray so, ‘sarvataḥ pāṇi pādaṃ, tatsarvatokṣi śiromukhaṃ’: near such a one, it is said, only ears stay and keep listening. ‘Swāmī! Do my sufferings not meet Your eye? Why can You not see all my sufferings?’ For those who pray like this, only eyes are near them. ‘Why should You not be behind me, beside me, in my home and before my eyes?’ For those who pray this way, God is always right behind them. But when will we hear this sound of footsteps?
