SB 4.28.41
saksad bhagavatoktena
guruna harina nrpa
visuddha-jñana-dipena
sphurata visvato-mukham
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this way King Malayadhvaja attained perfect knowledge because in his pure state he was directly instructed by the Supreme Personality of Godhead. By means of such enlightening transcendental knowledge, he could understand everything from all angles of vision.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this verse the words saksad bhagavatoktena guruna harina are very significant. The Supreme Personality of Godhead speaks directly to the individual soul when the devotee has completely purified himself by rendering devotional service to the Lord. Lord Krsna confirms this also in Bhagavad-gita (10.10):
tesam satata-yuktanam
bhajatam priti-purvakam
dadami buddhi-yogam tam
yena mam upayanti te
“To those who are constantly devoted and worship Me with love, I give the understanding by which they can come to Me.”
The Lord is the Supersoul seated in everyone’s heart, and He acts as the caitya-guru, the spiritual master within. However, He gives direct instructions only to the advanced, pure devotees. In the beginning, when a devotee is serious and sincere, the Lord gives him directions from within to approach a bona fide spiritual master. When one is trained by the spiritual master according to the regulative principles of devotional service and is situated on the platform of spontaneous attachment for the Lord (raga-bhakti), the Lord also gives instructions from within (tesam satata-yuktanam bhajatam priti-purvakam/ dadami buddhi-yogam tam). This distinct advantage is obtained by a liberated soul. Having attained this stage, King Malayadhvaja was directly in touch with the Supreme Lord and was receiving instructions from Him directly.
