I do not think the two questions you put are of much importance from the viewpoint of spiritual sadhana.
The question about science and spirituality would have been of some moment some twenty years ago and it filled the minds 
of men in the earlier years of the twentieth century, but it is now out of date. Science itself has come to the conclusion that it cannot, as it once hoped, determine what is the truth of things
or their real nature or what is behind physical phenomena; it can only deal with the process of physical things and how they come about or on what lines men can deal with and make use of them. In other words, the field of physical science has been now definitely marked off and limited and questions about God or the ultimate reality or other metaphysical or spiritual problems are outside it. This is at least the case all over continental Europe and it is only in England and America that there is still some attempt to reason about these things on the basis of physical science. The so-called sciences which try to deal
with the mind and men (psychology etc.) are so much dependent on physical science that they cannot go beyond narrow limits. If science is to turn her face towards the Divine it must be a new science not yet developed which deals directly with the forces of the Life world and of Mind and so arrives at what is beyond Mind, but present-day science cannot do that.
From the spiritual point of view such temporary phenomena as the turn of educated
Hindus towards materialism are of little importance. There have always been periods when the mind of nations, continents, cultures
turned towards materialism and away from all spiritual belief. Such periods came in ancient Europe in the first century A.D., in western Europe in the nineteenth
century
, but they are usually of short duration. Western Europe has already lost its faith in materialism and is seeking for something else, either turning back to old religion
or groping for something new. Russia and Asia are now going through the same materialistic wave. These waves come because of a certain necessity in human development – to destroy the bondage of old forms and leave a free field
for new truth and new forms of truth and action in life as well as of
what is behind life.
