In the Pure Mind, He is Seen
The same idea is expressed again:
न संदृशे तिष्ठति रूपमस्य
न चक्षुषा पश्यति कश्चनैनम् ।
हृदा मनीषा मनसाऽभिक्लृप्तो
य एतद्विदुरमृतास्ते भवन्ति ॥ ९॥
na saṃdṛśe tiṣṭhati rūpamasya
na cakṣuṣā paśyati kaścanainam .
hṛdā manīṣā manasā’bhiklṛpto
ya etadviduramṛtāste bhavanti .. 9..
His form is not an object of vision; no one beholds Him with the eye. One can know Him when He is revealed by the intellect free from doubt and by constant meditation. Those who know this become immortal.
Commentary:
Those persons become immortal and deathless who are able to visualise inwardly, by insight, that great light which cannot be beheld through the sense organs. This form of the supreme essence is not to be comprehended within the field of ordinary ocular vision. No one can see Him with the eyes. All-pervading is that Being. How would you see that, inasmuch as it is not an object of the senses? That Great Being is revealed in actual insight and intuition, which arises in your own heart, in the Atman. Having known this, you are immediately selected as heir apparent to the throne of the Immortal Being.
Swami Vivekananda Says —
None sees Him, none sees His form with the eyes. It is in the mind, in the pure mind, that He is seen, and this immortality is gained. When all vain desires of the heart have been given up, then this very mortal becomes immortal, then he becomes one with God even here.
When all the knots of the heart are cut asunder, then the mortal becomes immortal, and he enjoys Brahman here. Here, on this earth, nowhere else.[Source]
