Tantra is awareness.
It is about an enhanced body awareness of deeper sense of your own "energy".
For many of us, Tantra appears to be esoteric. In that case, educational tools, such as books, videos you tube and "googling:, are a great ways to develop an understanding of energy and its function.
One common entry point to Tantra is erotic massage with tantric techniques, Often, breathing practices are combined with extended arousal to create intense sensation, feeling of bliss and more.
Tantric self-pleasuring is a fun way to get more connected to your own body and to experience e the potential for tantric sex.
Also, there are non sexual tantric practices, such as meditation, mindfulness, yoga movements, breathing exercises that connect you to a deeper awareness of your potential as a human being. Over time, these practice tends to evolve to a felt sense in your body and the benefits to enhance your life.
To me, first and foremost,. Tantra is A PRACTICE. The purpose of a practice is to achieve results, Just like, physical exercise is meant to achieve better physical health. Similarly, a regular tantric breath practice helps to calm the mind, create a relaxed state of being and awaken erotic energy. That is a basic starting point. There is so much more to erotic energy and its use in life. Step by step, level by level, you will gain an expanded experience and its application to your own life goals.
