Prabhupāda:
- yaḥ svānubhāvam akhila-śruti-sāram ekam
- adhyātma-dīpam atititīrṣatāṁ tamo 'ndham
- saṁsāriṇāṁ karuṇayāha purāṇa-guhyaṁ
- taṁ vyāsa-sūnum upayāmi guruṁ munīnām
- (SB 1.2.3)
So, yaḥ svānubhāvam akhila-śruti-sāram ekam. Akhila means "entire." Read the word meanings. (Pradyumna leads synonym recitation)
Pradyumna: Translation: "Let me offer my respectful obeisances unto him (Śuka), the spiritual master of all sages, the son of Vyāsadeva, who, out of his great compassion for those gross materialists who struggle to cross over the darkest regions of material existence, spoke this Purāṇa, supplement to the Vedas, the cream of Vedic knowledge, after having personally assimilated it by experience."
Prabhupāda: So these are the qualifications of the spiritual master. What is that? Svānubhāvam, "must assimilate personally." Svānubhāvam akhila-śruti-sāram. Śruti. The Vedas are called śruti, absolute knowledge. It has to be learned by hearing, not by speculation. Śruti. Tad-vijñānārthaṁ sa gurum evābhigacchet śrotriyam (MU 1.2.12). From śruti, the śrotriya comes. So he's offering respect to Śukadeva Gosvāmī because he has assimilated the whole Vedic knowledge. Śruti-sāra. What is that sāra? Sāra means essence. What is the ultimate goal of knowledge, essence of knowledge? This is also explained in Bhagavad-gītā: vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). The real purpose of Vedic knowledge is to search out where is Kṛṣṇa.
So Śukadeva Gosvāmī assimilated the Vedic knowledge and he was after Kṛṣṇa. Although he was liberated soul, still, he was after Kṛṣṇa. To become liberated is not the final stage. Liberated means one who understands that he is not this material body—he is liberated. But that much knowledge is not sufficient. One must act according to that. Just like one is cured of the feverish condition. One was suffering some fever; now there is no fever. That's nice. But that is called convalescent stage. In the convalescent stage, if we do not take care nicely, again the fever may be relapse. That is marginal stage. We must come this side or that side. So even if we are liberated, if we are not engaged in the activities of liberation, then we are to be considered on the marginal stage. And marginal stage means we may fall down in this material condition. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ (SB 10.2.32). Āruhya kṛcchreṇa. Kṛcchreṇa means with great difficulty. The philosophers, they try to understand the Absolute Truth by mental speculation. But simply by mental speculation you cannot stay in that understanding. Or, in other words, by theoretical knowledge you cannot escape. It must be practiced. Practiced.
