Thank you Jhanananda, the advice is very helpful. I already do some yoga stretches mainly upward and downward dog, I will begin trying other ones like the hero pose to help the legs.
Regarding my legs, I usually sit in the half-lotus. I wish to move into the lotus position one day though.
Yes, I found downward dog useful for improving the length and comfort of my long meditation sits. I also found placing the soles of the feet together and stretching the knees down also helped a great deal.
On the full and half lotus,
I have found the posture overly hyped, as comfort is critical, not posture, and those who have a reputtion of promoting posture so far have not demonstrated an understanding of depth in meditation.
My session tonight was quite successful. I managed to enter Jhana after only 20 min into the session. I had trouble deepening it though so I would go back to the meditation symbol once in awhile then back to the charisms. How would one increase the depth of the first jhana. I wanted to first focus on mastering entering and exiting the first jhana before moving on. I tried experimenting a few times by trying to leave jhana by moving around while seated or playing with random thoughts so that distractions would dampen the jhana and then focus on the object again to re-enter jhana. Hard to say if it worked since I felt the charisms throughout most of the session.
In my experience the best way to deepen the depth of the meditation experience is simply to attend to the charisms (signs, jhana-nimitta) as the new meditation object, and to forget about any cognitive effort, while working to still the mind.
I am trying to follow along with this passage below
The perfecting of the first jhana involves two steps: the extension of the sign and the achievement of the five masteries. The extension of the sign means extending the size of the counterpart sign, the object of the jhana. Beginning with a small area, the size of one or two fingers, the meditator gradually learns to broaden the sign until the mental image can be made to cover the world-sphere or even beyond (Vism. 152-53; PP.158-59)
Following this the meditator should try to acquire five kinds of mastery over the jhana: mastery in adverting, in attaining, in resolving, in emerging and in reviewing.[16] Mastery in adverting is the ability to advert to the jhana factors one by one after emerging from the jhana, wherever he wants, whenever he wants, and for as long as he wants. Mastery in attaining is the ability to enter upon jhana quickly, mastery in resolving the ability to remain in the jhana for exactly the pre-determined length of time, mastery in emerging the ability to emerge from jhana quickly without difficulty, and mastery in reviewing the ability to review the jhana and its factors with retrospective knowledge immediately after adverting to them. When the meditator has achieved this fivefold mastery, then he is ready to strive for the second jhana.
First the Visudhimagga is clealry not an authoritive discourse on jhana, but is clearly an example of apporopriation, subvertion and obfuscation, so the only value of it is as evidence of the corruption of the Buddha dhamma. Just avoid any activation of the cognitive, while seeking to still the mind, while attending to the charisms (signs, jhana-nimitta), while relaxing deeply, and stilling the mind.
In my situation, would my sign be the warmth and vibrations? I felt it primarily in a bit of my arms but mostly along my spine and head. So I'm guessing my next step would be to get the vibrations and feeling of piti to surround my entire body? I'm unsure of how to broaden such a tactile sign to expand beyond my body though.
Just submit yourself to the natural process of deepening and opening in the experience of depth, like a flower blooming. The plant does not make the flower bloom out of effort. It just happens. In the same way, the contemplative should just sit everytime in meditation developing a still mind, while submitting to the depth that occurs in the experience of samadhi, which opens naturally likke the blooming of a flower in its own time.
Yes, the feeling of warmth and vibration are charisms (sign, jhana-nimitta), but it is not the job of the mystic to make it do anything, but just to observe it, and submit to it.
I found the excerpt from an article on your site here http://www.greatwesternvehicle.org/ati_website/lib/bps/wheels/wheel351.html#ch3.3
The GWV website in the dhamma study section attempts to offer a broad understanding of the dhamma, so some of what we have there is not necessarily correct. So, I would not recommmend paying too much attention to the Wheel articles. I suggest instead you pay attention to the section that is dedicated to our communitie's direct experience of the 8 stages of samadhi.
