When advancement of knowledge is applied in the service of the Lord, the whole process becomes absolute. The Personality of Godhead and His transcendental name, fame, glory, etc., are all nondifferent from Him. Therefore, all the sages and devotees of the Lord have recommended that the subject matter of art, science, philosophy, physics, chemistry, psychology and all other branches of knowledge should be wholly and solely applied in the service of the Lord.
Scientific knowledge engaged in the service of the Lord, and all similar activities, are all factually hari-kīrtana, or glorification of the Lord.
The brahmanas, who are always engaged in researching knowledge for the society's welfare work, both materially and spiritually, deserve the protection of the king in all respects. SB1.14.41
Just like in India, for higher technological knowledge, they come to foreign countries. So for knowledge, we can take it from anywhere. There should not be sectarianism, “Oh, why shall I take knowledge from here and there?" Wherever knowledge is available, we should take it. That is the real position of seeker of knowledge.
