Krishna guides the sincere soul through the spiritual master externally and the Supersoul within simultaneously.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 2.9.7 — April 26, 1972, Tokyo 720426SB-TOKYO [18:05 Minutes] SB-02.09.07_720426SB-TOKYO Pradyumna: [leads chanting of verse] ..āsthāya vimṛśya tad-dhitaṁ tapasy upādiṣṭa ivādadhe manaḥ [SB 2.9.7] Prabhupāda: Now, chant. Recite. [devotees chant verse] niśamya tad-vaktṛ-didṛkṣayā diśo vilokya tatrānyad apaśyamānaḥ svadhiṣṇyam āsthāya vimṛśya tad-dhitaṁ tapasy upādiṣṭa ivādadhe manaḥ Prabhupāda: Yes. Very good.
Transliteration is coming to be useful. Yes. Next. [break] The transliteration is there for you.
So although you are selling books, but this is meant for you, so that you can [indistinct] the mantras. Who is next? [lady devotee chants] [break] Pradyumna: "...searching on all sides. But when he was unable to find anyone besides himself, he thought it wise to sit down on his lotus seat firmly and give his attention to the execution of penance, as he was instructed." Prabhupāda: So he could not find any person.
Still he took it seriously and began tapasya. Therefore in the beginning of Bhāgavata it is said, tene brahma hṛdā ādi-kavaye: "From heart." Yes. He heard from outside. From the heart the order was, "Yes, now you begin your tapasya." So he began.
So Kṛṣṇa is helping both sides—from externally, internally. Externally he heard—somewhere the sound came—and internally He confirmed, "Yes." So Kṛṣṇa is helping us externally by the spiritual master, internally by instruction[?]. Buddhi-yogaṁ dadāmi [Bg. 10.10]. In this way, He is trying to help us. Unfortunately we do not care to take His help.
Then why should we not suffer? Antar-bahiḥ. Antar-bahiḥ. There are two things: inside and outside. So Kṛṣṇa is...
Outside He is helping, spiritual master. Spiritual master is external manifestation of the Supreme Lord. Just like if somebody is going somewhere in this Tokyo city, I have to say something, so I apply him, "Will you kindly carry this message to him?" Similarly, Kṛṣṇa deputes some of His confidential devotees to help the people to become Kṛṣṇa conscious: "Please go and tell him this." The spiritual master is, therefore, external manifestation of the Supreme Lord. And internally He is sitting there as Paramātmā.
