Though seed is the primary cause for the birth of a plant, there are many other cooperating forces in play that will affect the growth of the plant.

Similarly, Enlightenment itself is not related to time and location. When there is darkness, only light can remove the darkness. Knowledge alone will remove the ignorance within us. However, gaining this knowledge requires immense Tapasya. Practicing yoga and meditation becomes easy when there is less noise and nice weather. Time and location are cooperating factors, not the cause for enlightenment. If location was the cause for Enlightenment, everybody living in Bodh Gaya would have been a Gyani. But, it is not so. Solitude and renunciation are two important cooperating factors if one really wants to achieve the pinnacle of yoga.
