Namaskar everyone!

My account name is Mahaindra and i am new to the forum although i have been following for a while and have been very impressed the knowledge and diversity of opinions. So, a little on my story. I was born in a proud indian sikh family in London growing up i cherished hearing stories about Sikhi but also stories of Shri Ram and Sri Rudra. In recent times, i have found myself incredibly close, developing a relationship with sanatana dharma, i wish to learn the stotrams and the Lalitha sahasranamam' , but understand i must be initiated under a guru, learning sandhyavandanam. What is the process one must do this and what are the rules for upanayanam and initiation how can i do this? Namaskar and Pranam
