Yes, self-inquiry can definitely be practiced alongside other spiritual practices. In fact, many spiritual teachers and practitioners recommend incorporating self-inquiry into one's daily spiritual routine.

Self-inquiry, as taught by Ramana Maharshi, is a powerful method of liberation that involves questioning the nature of our true self. By constantly asking ourselves, "Who am I?", we are able to peel away the layers of conditioning and false identities that we have accumulated over time. This leads us to the realization of our true nature, which is pure consciousness or the "I am" presence.

While self-inquiry can be practiced on its own, it can also be combined with other spiritual practices such as meditation, yoga, and mindfulness. These practices can help to quiet the mind and create a conducive environment for self-inquiry. They can also help us to become more aware of our thoughts and emotions, making it easier to identify and let go of the false identities that arise during self-inquiry.

Moreover, self-inquiry can enhance the effectiveness of other spiritual practices. For example, by constantly questioning "Who am I?" during meditation, we can deepen our understanding of our true nature and experience a more profound state of inner peace and stillness. Similarly, incorporating self-inquiry into our yoga practice can help us to let go of any physical or mental tensions and connect more deeply with our true self.

It is important to note that self-inquiry should not be seen as a separate or exclusive practice. Rather, it can be seen as a way of approaching all aspects of our spiritual journey. By constantly questioning our true nature, we can bring a sense of mindfulness and awareness to all our actions and experiences, allowing us to live in a state of inner peace and contentment.

In conclusion, self-inquiry is a powerful tool for liberation that can be practiced alongside other spiritual practices. It can enhance the effectiveness of these practices and help us to deepen our understanding of our true nature. So, whether you are new to self-inquiry or have been practicing it for a while, incorporating it into your daily spiritual routine can bring about profound transformation and lead you to a state of inner freedom and joy.
