Kinds of meditation/asana

The best form of meditation is to sit in Sidhasana or Padmasana (lotus pose), sit erect, close the eyes, concentrate on the ‘Trikuti’, make the mind free of all thoughts and imagine the empty space (which results after closing the eyes) as the empty universe (as it was before ‘Sristi’ or creation) occupied by the ‘Nirguna Brahman’ (formless Almighty) who is colorless, shapeless, invisible to the naked eye, all powerful, all pervading and stretching to infinity. One should take the mind into ‘Shunya’ (zero thought) and consider oneself as no different from this empty space occupied by the formless Lord. Whenever thoughts arise, they should be displaced, reminding oneself that this world is unreal and hence the thoughts connected to this world are also false. Again, the mind should be merged back into this empty space occupied by the Almighty. This way, one merges the mind and the ‘Ahamkara’ (ego or lower self) into pure Buddhi or I-ness. While trying for this Samadhi, one should be aware – “I am not the body, not the mind, not the Aham or Ego. I am only the Atman who is one with the Brahman represented by this empty space and have now merged into the Lord. This is my true form, stretching to infinity. This person called ME longer exists. It is gone and I have merged into the Lord”.

It will take many years to get established in this process called ‘Nirguna Dhyana’ (meditation on the formless Lord.) When one is established in this state where there is no thought but only emptiness of merger, it is called Savikalpa Samadhi. In this Samadhi, there is only pure ‘Asmita’ or pure awareness of ‘I’ without any desire, worry, anger or fear. One feels as though floating in an infinite ocean, clear and free of all thoughts except the thought “I have become one with the formless Lord”. When one can maintain such a state of freedom from thoughts but with only the pure I – ness for a long time with effort, it is called ‘Ekagrata Parinâma’ (one pointed condition). On attaining to perfection of this state after thousands of hours of such meditation, the Yogi who has striven very hard with great sacrifice towards unbroken Brahmacharya becomes an ‘Urdhvareta’. Such a Yogi does not get wet dreams. He gets deep and flawless Nidra (sleep) at night.

When meditation is carried out on God with form (as in an idol or photo) by imagining the form of God at the Trikuti after closing the eyes, it is called ‘Saguna Dhyana’ (meditation on God with form). This can be practiced by beginners if they are unable to practice ‘Nirguna Dhyana’. Upon reaching the stage where they get no other thought but the thought of the form of God, they can shift to ‘Nirguna Dhyana’. Saguna Dhyana is a preliminary method which eventually turns into Nirguna Dhyana upon perfection.

2. Continue with the regular Yogic practice and meditation. These dreams are the result of past Samskara-s (impressions) and Vasana-s (tendencies) that surface when leveraged by Yoga. The way to remove them is through honest Yoga and a life of purity. There is no other method. They will gradually lessen and finally go away in course of time if the practice is honest, regular and unbroken for a long time. If the tendency for a wet dream arises, a very vigilant and devoted Yogi will be able to perform ‘Mula Bandha’ even in the dream and thereby reduce the possibility of copious discharge.

3. Many different Asana-s can be practiced before commencing Bandha. These have been mentioned in past answers. Sidhasana or Padmasana (lotus pose) are chosen as a sitting pose for Bandha, Nadi Shodhana, Pranayama and meditation.
