Truth means never taking anything to be true without proper proof. It does not mean an accumulation of certain external observations of objects. It is an attitude, an outlook, a method. The truth must be based on verification through inquiry, analysis and reasoning. But seeker has to cultivate the attitude of getting proof by using reason.
Modern Science rules the world. It offers something of practical value to the practical life within the practical world.
To stick to what one considers is real, and not because it is true, is perversity. Unless it is proved to be true, one should not accept it. He who knows that ultimate truth which can be grasped by reason, study, he moves not from truth. Reason based on the true self is means to reality.
Some conceited pundits say reason cannot grasp the Self: it is formless. True it is unattainable to those who are not receptive , who have not inquired analyzed and reasoned, but it possible for those who have are receptive and courage to accept the truth and reject the untruth after verification of the facts. Seeker has to reflect over it all again and again until his conviction of the true self becomes firm.
Attaining perfection of Self-Knowledge or Brahma Gnana or Atma Gnana is the goal of the truth seeker . Religion and Yoga are not the means to acquire Self-Knowledge or Brahma Gnana or Atma Gnana . Only soul-centric reason takes the mind towards the source from where it has been erupted.
The greatest weakness of the yogi is to think what has given me peace is true. The yogi lulls the senses into blissful slumber, renders truth impossible. He has to be awakened! Yoga takes one away from the path of truth.
Yogic Samadhi-bliss or the sexual pleasure are not the means to acquire ultimate truth or Brahman because they are practiced on the false self(ego or waking entity) within the false experience(waking). When the self is not form but self is formless soul than how yoga and sex can yield truth.
If one holds the waking entity as self it is impossible to realize the ultimate truth or Brahman. Seeker should by effort be drawn back his attention of the formless substance witness of the three states, that alone yields ultimate truth or Brahman .
Modern Science is the highest teaching in the world of duality. Spirituality has its roots in the same world, but ultimately leads to non-duality.
