True knowledge is knowledge of eternal truth.

The knower, that which is to be known, the means of knowing, and the acquired knowledge.

By three means.

Awareness of the senses contacting an object.

Yes, perception is subject to four defects.

No. The material senses have no capacity to perceive eternal reality and have very minute capacity to perceive even material objects.

Reaching a conclusion based on a proposition, cause, and precedent, and perception.

No. All forms of inference are based on sense perception and subject to the same defects that sense perception is.

Revelation is testimony from a trustworthy source.

Divine revelation is the one and only means to attain true knowledge.

Perception and inference assist us in receiving revelation of true knowledge.

Eternal truths are imperceptible, inconceivable, fundamental, and wonderful.

In the Vedas.

The rishis ‘see’ eternal truth only because it is revealed to them by the Supreme Lord.

He is merciful.

There is only one way to know: follow the path they prescribe.

We need to be resolute that such endeavour is the sole means to our welfare.
