How to Meditate Properly
Patanjali, the highest authority on the science of yoga, provides the best meditation (Dhyana) technique: तत्र प्रत्ययैकतानता ध्यानम् ॥3.2॥ Tatra pratyaya ikatanata dhyanam (3.2 Patanjali-Yoga sutra) तत्र- प्रत्यय- एकतानता-ध्यानम् जिस स्थान पर धारणा की गई हो, उस धारणा का लम्बे समय तक बने रहना ध्यान कहलाता है । Meaning: When you use concentration (dharana) to direct all of your awareness toward a single form or thought, you are in meditation.
