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:
- śruti-smṛti-purāṇādi-
- 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 the all these books, if anyone poses himself that he has understood God and devotional service, it is simply disturbance, creating disturbance. That's all. Śruti-smṛti-purāṇādi . . . 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.
