Philosophy is the science that unites vast majority of sciences by defining common notions and laws. That is why it is more adequate to define philosophy as science about most general notions (categories, or truths) and laws that connect these notions in a certain area of objectibve reality. So, materialism is philosophy of material, or phisical world, idealism is philosophy of thinking, gnoseologi is philosophy of cognition, there is philosophy of human and so on. Humanity builds knowledge about the world either by using sense organs (the "pictured" world) or by receiving the information from the people with more developed thinking (parents, educators, teachers). The latter process gives understading of the nature of things,  in other words, receiving knowledge and development of thinking abilities under learning process is much more effective comparing to the independent learning about the world around.

When analyzing the western philosophy under the structural approach, it becomes clear that it is not structured enough (there's no complete set of basic categories and laws that relate them to each other). If we turn to vedic philosophy and analyze it under structural approach, we see the opposite: there are such basic categories of the world (truths) as God, spiritual and material energies. Two more categories can be added, namely time and karma.The connections between these categories are described in the philosophical work "Bhagavad Gita". Based on mentioned categories, Bhagavad Gita describes each of the element of this structure consequently. That is why we think that a relevant and effective way of further shaping knowledge about the objective reality would be to integrate so called western sciences that produce deep knowledge of the physical world with vedic philosophy that contains wholesome and summarized knowledge about the universe.
