This is an EBook "HR-201: “Principles and Practice of Hindu Religion”. It explains the principles and philosophy in detail for the students about the Religion as a Dharma of the teachings in 108 lessons. Hindu Religion is a very ancient culture and tradition. This is the third most popular religious practice in the world. Hindu religion is practiced as a lifestyle or Dharma by more than a billion people in its various paths and forms, with unity within the diversity that is seen. It includes several millions in addition, who follow alternate paths of practices given by later-day teachers including those who are Atheists and Nãsthika who do not believe in a God as a Supreme force. These are useful lessons for an outsider to get a glimpse about the traditions to get an understanding of the same. These lessons are useful for practicing Hindus around the world to get the proper understanding of the several paths in their faith and to teach the same to their children and to prepare the future generation to live in peace with others and within themselves. The various forms of practices are explained along with the true Unity in the principles that lies beneath the diversity in these various paths being taught. They also will understand the great traditions and the great knowledge of the ancient sages that has been passed on to generations after generations. They also teach the paths of meditation and concentration along with devotional prayers and rituals to give them a peace of mind and to gain the prosperity in life. This is written by me and was earlier published as a hard-copy book in 1999 in its first edition. This was extensively followed by many around the world to understand all aspects of this religious faith. This book was shown as a reference book in many universities in many countries. The second edition is produced as an EBook through Amazon Kindle, also can be read on other computers, smart phones and tablets with kindle readers. This second edition has been extensively reviewed and updated.
