When we have compassion towards another, we become fearless in our interactions with them. Meditation awakens compassion and helps us become fearless. Picture Credits: Nitu Chhajer's Art. To purchase this painting call Saurabh @ +919945131095.
There is a part of us that wishes to change the way things are. When this part becomes active during meditation, it gains power if we wish to change things. If instead we simply observe it and return to our intention to be one with our breath, we can end the cycle of action faster. Awareness itself is enough to transform whatever image comes up. The thing to do it to increase the awareness. Awareness is like the fire under the cooking pot. If the soup is not cooking fast enough, we have to increase the flame (awareness). Stirring the pot is not going to make it cook faster. Be dedicated to awareness. It is the key.
Every science has its own exclusive terminology. The science of music has many different Ragas, Shrutis, Layas, and Talas. Similarly, the science of meditation has its own terminology. Chakras are one such terminology. Meditators will often start perceiving energy movements in their bodies that correspond to Chakras. One of the Good places to read about Chakras is this article on Deepak Chopra's website : http://www.chopra.com/articles/what-is-a-chakra .
Even though the lotus posture is one of the most stable postures for meditation, it is not essential for practising meditation. In fact, forcing yourself in an uncomfortable or painful position will only hamper your ability to meditate. You can sit in Lotus position, half-lotus position, kneel down, sit on a chair or stool, or even lie down. Source: Art and Science of Meditation - by Ms. Chitra Jha and Dr. Newton Kondaveti.
