All people are shallow in their understanding of Truth. They mistake religious play to be genuine religion. They don't know that they must meditate to reach that Truth, to reach the Self.
External worship without sincere desire to unite with God and without meditation is a form of sense gratification and in itself actually masks the Self with illusion, delusion and error. Genuine religion means to unite with God, who is the Self. The Kena Upanishad 1:2 says:
"He is the Ear of the ear, the Mind of the mind, the Speech of speech, the Life of life, and the Eye of the eye. Therefore an intelligent man after giving up self-identification with the senses and renouncing this world becomes immortal."
The truly intelligent person is one who sincerely desires self-realization and meditates to achieve this supreme goal. To become self-realized, requires humbly approaching a genuine spiritual master, asking him questions to clarify your understanding and have him impart his divine knowledge, infuse you with divine energy and guide you in meditation. Try and taste.
You must meditate more and more and more. Then you must apply this meditation in your daily life. Watch Him in your every movement, thought, work and disposition. You will learn to objectively separate your personality, or ego, from your true Self. You will see that God is the doer in every thought and action
