Guru darshan means to realize each and everything meant for Guru-puja not for our sensual enjoyment. Whereas laghu darshan means to watch everthing with enjoying mood. The term “Darshan” is not the perfect translation of the word Philosophy because Philosophy the word going to invite some imaginary conception, whereas darshan the word means as it is what is what. Truly speaking Bhajan means to rectify our dirty material darshan. From Srimad Bhagavatam we know the following sloka which can give evidence in favor of our above discussion.
yathā yathātmā parimṛjyate ’sau
mat-puṇya-gāthā-śravaṇābhidhānaiḥ
tathā tathā paśyati vastu sūkṣmaṁ
cakṣur yathaivāñjana-samprayuktam (ŚB 11.14.26)
When a diseased eye is treated with medicinal ointment it gradually recovers its power to see. Similarly, as a conscious living entity cleanses himself of material contamination by hearing and chanting the pious narrations of My glories, he regains his ability to see Me, the Absolute Truth, in My subtle spiritual form.
