True Yoga Requires Following Hindu Gods

There is a misconception that Yoga has nothing to do with Hinduism or idol worship.  Sure, the positions and stretches are beneficial and bring healing to the body, but one should never indulge in such practices without first being aware of what one is signing up for in the long run.

If all you want is to get a good stretch and loosen up your overall flow of blood and energy in your body, then fine, but if you ever find yourself looking for inner peace and meditation, then you are playing with fire.  Plus, one cannot ignore all the pictures of Hindu idols, the statues, the incense, and the music played to entice Hindu worship and rituals.  I bet if you simply ask any of the other participants in your class about their faith, the majority will confess that they believe in Karma and Reincarnation and that all gods are the same.  It seems like this practice is not as innocent as you might believe it to be. 

Another fact about Yoga that is not talked about frequently is that it uses the power of Kundalini, which is the coiled (snake like) spirit located at the base of the spine. Through these extreme postures and stretches one tries to liberate this spirit within one’s body. This spirit is a feminine one and one of its ultimate goals is to use Tantric power for seduction and the enhancement of sensation during sexual practices. 
So the question to ask ourselves is…Can Yoga be separated from Hinduism?
Here are some Hindu scriptures from the four most important books on yoga, so that you can decide for yourselves:
1.) Hatha Yoga Pradipika: When we talk about different yoga poses (asanas), we are talking about Hatha yoga. The book opens like this “Salutation to the glorious primal guru, Sri Adinath who instructed the knowledge of Hatha yoga (Chap 1.1).”
2.) Gheranda Samhita: In the second chapter, it begins like this “There are eighty-four hundreds of thousands of asanas described by Shiva. Among them are Padmam, Kurma, Vriksha asanas (Chapter 2.1-6).”
3.) Shiva Samhita: In this book, we get to see how by practicing yoga or simply by chanting the word AUM the practitioner destroys his past and present karmas. This proves one has to believe in reincarnation/karmic theory before starting to do real yoga (Chapter 3.48-51). We also find mention of several Hindu gods’ names over and over again in Chapter 2 + Chapter 5. We find the names of Brahma, Vishnu, Shiva, and Saraswati which cannot be erased from the teachings about yoga.
4.) Yoga Sutras of Patanjali: In chapter 2.44-45 it says “By study comes communion with the lord in the form most admired. Realization is experienced by making the lord the motive of all actions.” Who is the lord here? In Sanskrit here in this verse, the word is Isvarapranidhana which means surrendering or being devoted to this “god” while studying the philosophy of yoga.
But devoted to whom? As we know before a yogi starts doing yoga, the word AUM is chanted, the Yoga Sutras say in chapter 1.27-28, it is the sound of the supreme lord (Shiva).
Yoga is Hinduism and Hinduism is yoga.
