Vedic ideologies are contained in Brahmi; the oldest root of all the languages. Modern commentators perceived Vedas are in Sanskrit and doing distorted interpretation. So Veda is not understood. There are very few, nearly, 10-12 Brahmi language experts there in India. Rest of the scholars are interpreting from the roots of Sanskrit. Hence Veda has become complex, unsolvable mystery. To understand Vedas one has to learn Brahmi language, identify the word differences caused by the incomplete scripts from other languages, revise the words with respect to original language, then of course Veda will reveal itself to you and becomes understood. Else, Veda might be perceived as an unsolvable mystery, which is due to one's wimp.
How to understand Vedas? First learn one of the efficient Indian languages and get become language expert. Try to learn Brahmi from the known finger countable people. Practice Brahmi based Vedic grammar. Do hard work, study and practice 54 Aksharas - Alphabets, 10 Sanjnas - Signs, 7 Bindus - Points (E.g., Nasalized Vowels), 13 Sutras - formulas. Its called as Akshara Vidhya. In alternative approach, if an individual gains Akshara Vidhya, then will get the knowledge of Vedic language and thus the Vedas. First, practice alphabets - Akshara Abhyaasa in Brahmi (or at least a perfect Indian language, but not the business language like English). Gain the Aksha Vidhya. Then study Vedic literature. Practice the following Vedic Dasha Maha Vidhyas :
Vyakarana, Chandas, Swara, Maatraa, Prastaara,
Sanjna, Naadabindu, Laghu, Guru, Udaattha, Swaritha, Anudaattha ||
Attain the knowledge of these (10) Dasha Vidhyas and continue the Veda Paarayana - Chanting Vedas. Then Veda will become Vedya - Understood and experienced by itself. Then one will reach the altitude and could be really honored as Veda Murthy, Veda Brahma etc.,
