One should not just start reading the scriptures without guidance. The scriptures are called Sruti, which literally means "that which is heard" the hearing being from a competent teacher.
At the very start of his Sri Bhyasya (I.I.1.), Ramanuja in his commentary on the first verse quotes the Mundakya Upanishad (I.ii.12.) "To know that he...must approach a guru" etc.
In his writing Upadesa Sahasri, Sankaracharya says:
For the Srutis say, "A man having a teacher can know Brahman," [Chhandogya Upanishad 6.14.2.] "Knowledge received from a teacher alone (becomes perfect)." {Chhandogya Upanishad 4.9.3.] "The teacher is the pilot" "Right Knowledge is called in this world a raft," etc. The Smriti [Bhagavad Gita 4.34] also says "knowledge will be imparted to you" etc.
Swami Vivekananda says this story about Ramakrishna Paramahamsa:
Many years ago, I visited a great sage of our own country, a very holy man. We talked of our revealed book, the Vedas, of your Bible, of the Koran, and of revealed books in general. At the close of our talk, this good man asked me to go to the table and take up a book; it was a book which, among other things, contained a forecast of the rain during the year. The sage said, "Read that." And I read out the quantity of rain that was to fall. He said, "Now take the book and squeeze it." I did so and he said, 'Why, my boy, not a drop of water comes out. Until the water comes out, it is all book, book. So until your religion makes you realize God, it is useless. He who only studies books for religion reminds one of the fable of the ass which carried a heavy load of sugar on its back, but did not know the sweetness of it." (Complete Works I. p 326)
Find a teacher and he will guide you on what to read and when.
