This is the sign. Evaṁ prasanna-manaso bhagavad-bhakti-yogataḥ (SB 1.2.20). Then you can understand what is God. God is not so cheap: "Come on, I shall show you God. You haven't got to follow any rules and regulations." People want to be cheated. Therefore there are so many cheaters. They take advantage of it. Because they want everything very cheap. That is not possible. This is the stage, prasanna-manasa. Then you can understand what is God. Bhagavat-tattva-vi... Because it is a science. If somebody says, "Come on, I shall teach you the science of chemistry within a second. Give me some money," is it possible? If somebody says, "I shall teach you mathematics. Come on, give me some money.," So why these rascals are misled? If... It is a science; it is not sentiment. It is science. There was... Understanding of the Supreme Personality of Godhead without reference to these scientific books, Vedic literature, it is simply a disturbance, simply rascaldom. Simp... Because they are creating disturbance, always, cheating some people. They are cheated. They do not get anything. Create some disturbance. That is the instruction of Rūpa Gosvāmī.
- pañcarātra-vidhiṁ vinā
- aikāntikī harer bhaktir
- utpātāyaiva kalpate
- (Brs. 1.2.101)
Utpāta, utpāta means disturbance. So many rascals, without reference to the Vedic literature, revealed scriptures, Śruti-smṛti. These are Vedic literatures, śruti-smṛti-purāṇa, pañcarātra-vidhi. Without reference to all these books, if anyone poses himself that he has understood God and devotional service, it is simply a disturbance, creating disturbance. That's all. Śruti-smṛti-purāṇādi... (Brs. 1.2.101). Because it is a science. How you can manufacture it? It is not that thing.
Therefore any religion without scientific understanding through philosophy, it is simply sentiment. It is not religion. And philosophy without religious understanding is mental speculation. That is also useless. Philosophy which does not search ultimately what is truth, what is God, that philosophy is mental speculation. And the knowledge of God without philosophy is simply sentiment. They should be combined. To understand God, our relationship with God, our duty, everything should be understood, scientifically. Bhagavat-tattva-vijñānam. Therefore this word has been used, vijñānam. Viśeṣa-jñānam. Jñānam, ordinary knowledge, and vi, when the this word is added, vi, meaning viśeṣatā, particularly, for practical application... This vijñānam.
So this vijñānam, this science, can be understood by mukta-saṅga, who is freed from the lower modes of material nature, especially tamo-guṇa and rajo-guṇa. So do not be befooled by so many rascals that bhagavat-tattva-vijñānam, the science of God, understanding is so cheap that anyone can give you by simply one day's association with some rascal. You see. This is not so possible. Yes, it has to be studied, it has to be practiced. It has to be realized. So this vijñānam is being stated in the Śrīmad-Bhāgavatam. Therefore in the beginning, in the Śrīmad-Bhāgavatam: dharmaḥ projjhita-kaitavo 'tra (SB 1.1.2). All rascaldom going on under the name of religion, cheating religion, they're completely kicked out from Śrīmad-Bhāgavatam. Simply on scientific understanding we are presenting what is Kṛṣṇa consciousness. Not for sentimentalists. Read the purport.
