Prabhupāda: (sings "Govindam ādi-puruṣaṁ tam ahaṁ bhajāmi **.") So we are worshiping Govindam, the Supreme Personality of Godhead, the original person. So this sound, govindam ādi-puruṣaṁ tam ahaṁ bhajāmi, is reaching Him. He is hearing. You cannot say that He is not hearing. Can you say? No. Especially in this scientific age, when television, radio messages are broadcast thousands and thousands of miles away, and you can hear, now why can you...? Why Kṛṣṇa cannot hear your prayer, sincere prayer? How can you say it? Nobody can deny it. So, premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti (Bs. 5.38). Just like thousands and thousands of miles away you can transfer the television picture or your radio sound, similarly, if you can prepare yourself, then you can see always Govinda. It is not difficult. This is stated in Brahma-saṁhitā, premāñjana-cchurita-bhakti-vilocanena. Simply you have to prepare your eyes, your mind in that way. Here is a television box within your heart. This is the perfection of yoga. It is not you have to purchase one machine, or television set. It is there, and God is also there. You can see, you can hear, you can talk, provided you have got the machine. You repair it, that's all. The repairing process is Kṛṣṇa consciousness. Otherwise, everything is supplied, complete, complete set of machine you have got within you. And just like for repairing, an expert mechanic required, similarly, you require the help of someone expert. Then you'll see that your machine is working. It is not difficult to understand. Nobody can say that it is not possible. In the śāstra we hear also. Sādhu śāstra, guru vākya, tinete kariya aikya. Spiritual realization can be perfected by three parallel process. Sādhu. Sādhu means saintly persons, who are realized souls, sādhu. And śāstra. Śāstra means scriptures, authoritative scriptures, Vedic scriptures, śāstra. Sādhu, śāstra, and guru, a spiritual master. Three parallel line. And if you place your car or vehicle on these three parallel line, your car will go direct to Kṛṣṇa. Tinete kariyā aikya. Just like in the railway line you see two parallel lines. If they are in order, the railway carriages are carried very smoothly to the destination. Here also, there are three parallel lines—sādhu, śāstra, guru: saintly person, association of saintly person, acceptance of bona fide spiritual master, and faith in the scriptures. That's all. Then your carriage will be going nicely, without any disturbance. Sādhu śāstra guru vākya, tinete kariya aikya.
So here in the Bhagavad-gītā, the Supreme Personality of Godhead explaining Himself, Kṛṣṇa. So if you say, "How can I believe that Kṛṣṇa said? Somebody has written in the name of Kṛṣṇa that 'Kṛṣṇa said,' 'God said.' " No. This is called disciplic succession. You will see in this book, Bhagavad-gītā, Kṛṣṇa, what Kṛṣṇa said, and how Arjuna understood. These things are described there. And the sādhu, saintly person, beginning from Vyāsadeva, Nārada, down to many ācāryas, Rāmānujācārya, Madhvācārya, Viṣṇu Svāmī, and latest, Lord Caitanya, in this way, they have accepted: "Yes. It is spoken by Kṛṣṇa." So this is the proof. If saintly persons have accepted... They have not denied. Authorities, they have accepted, "Yes." This is called sādhu. And because sādhu, saintly persons have accepted, therefore it is scripture. That is the test. Just like... It is common sense affair. If the lawyers accept some book, then it is to be understood that this is lawbook. You cannot say that "How can I accept this is law?" The evidence is the lawyers are accepting. Medical... If the medical practitioners accept, then that is authoritative medical. Similarly, if saintly persons are accepting Bhagavad-gītā as scripture, you cannot deny it. Sādhu śāstra: saintly persons and scriptures, two things, and with spiritual master, three, three parallel lines, who accept the sādhu and the scripture. Sādhu confirms the scriptures and spiritual master accept the scripture. Simple process. So they are not in disagreement. What is spoken in the scripture is accepted by saintly person, and what is spoken in the scripture, the spiritual master explains only that thing. That's all. So via media is the scripture. Just like lawyer and the litigants-via media is the lawbook. Similarly, the spiritual master, the scripture... Saintly person means who confirms the Vedic injunction, who accepts. And scripture means what is accepted by the saintly person. And spiritual master means who follows the scriptures. So things equal to the same thing are equal to one another. This is axiomatic truth. If you have got one hundred dollars, and another man has got hundred dollar, and if I have got hundred dollar, then we are all equal. Similarly, sādhu śāstra guru vākya, when these three parallel lines in agreement, then life is success.
