Yog And The Flow Of The Four Ashrams
The vedic culture is a very scientific and precise science, science of entire creation and the science of being as a microcosm of the macrocosm which is the physically manifested creation.
After a stage a yogi needs to his/her limit interactions with normal people. There is a story in the Mandukya Upanishad about a group of rishis who used to live in Himalayas. One day these rishis suddenly realised that their bodies had started ageing. (A Yogi’s body does not age. He/she leaves the body in full consciousness and strength, being aware of where he/she is going.) The rishis then had a discussion on the possible reasons for ageing. They realised that this happened as they left their Himalayan abode to settle in the villages resulting in increased interactions with normal people. When you have interaction with normal people, there is intermingling of thoughts and energy patterns. And then the body begins to exhibit the symptoms of a normal human being - eat, drink & make merry. Vedic masters say, and modern science agrees that every action has an equal and opposite reaction. When you resort to pleasures of the five senses, as an equal and opposite reaction, the body begins to age. This ageing has to be held back to garner the energy to make the final journey beyond the five senses and also take the deserving shishyas beyond. So during the phase of vanprastha, you limit your interactions otherwise the body ages very fast.
Now let me give you the traits of a guru – a guru is someone who does not charge you a fee because someone who is him/herself tied in maya cannot release you, he/she exudes the glow and attraction associated with yog, diseases disappear in his/her presence, whatever he/she says happens, and he/she is sthir in the five yams,. So my suggestion is look for a guru, give the subject priority and you will be called on board on this beautiful journey called yog.
